Here\u2019s What It Said"},"content":{"rendered":"<p>A major change in this year&#8217;s itinerary planning is that I used GenAI tools &#8211; and a lot of it! I used it somewhat sparingly when planning for the 2025 itineraries, but this year was a major step-up in the extent of use. In fact that I very quickly busted what was provided in the free tier of services, requiring that I pay a subscription fee to get tools like ChatGPT to do more complex analyses. Yes, I&#8217;m well aware that these tools should be used with a fair bit of salt and discretion, so I always rechecked using the old ways (e.g. web searches) what the GenAI tool was saying, especially pertaining to things like opening hours, traveling distances, whether places were really any good.<\/p>\n<p>That out of the way, I used ChatGPT this year to especially:<\/p>\n<p style=\"padding-left: 40px;\">Stylize my itineraries to make them look consistent, and also check for typographical errors and timing errors.<\/p>\n<p style=\"padding-left: 40px;\">Got it to analyse the vacation posts this blog to understand my preferences (e.g. scenery yes, religious sites not really), what I look out for in vacations (e.g. minimal changes of accommodations), and things which are deal breakers for me (e.g. crowds!)<\/p>\n<p style=\"padding-left: 40px;\">Analyse the visit durations of each place to make sure I wasn&#8217;t overspending\/underspending the amount of time.<\/p>\n<p style=\"padding-left: 40px;\">Analyse time to get from place to place, including accommodations, and ensuring sufficiency and buffers during peak hours.<\/p>\n<p style=\"padding-left: 40px;\">Analyse which days are physically demanding and propose adjustments.<\/p>\n<p style=\"padding-left: 40px;\">Analyse the range of sights to ensure there&#8217;s a balance and avoiding repeated sight types.<\/p>\n<p>In short, these tools are very useful for checking and proposing micro adjustments. They can of course also propose entire itineraries for you, but I wanted to do that sort of higher level planning.<\/p>\n<figure id=\"attachment_37958\" aria-describedby=\"caption-attachment-37958\" style=\"width: 1000px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-37958 size-full\" src=\"https:\/\/www.chekyang.com\/musings\/wp-content\/uploads\/2026\/03\/2006-Honeymoon-Korea-210-PICT2657-Day3-Oedolgae-Jeju.jpg\" alt=\"\" width=\"1000\" height=\"665\" srcset=\"https:\/\/www.chekyang.com\/musings\/wp-content\/uploads\/2026\/03\/2006-Honeymoon-Korea-210-PICT2657-Day3-Oedolgae-Jeju.jpg 1000w, https:\/\/www.chekyang.com\/musings\/wp-content\/uploads\/2026\/03\/2006-Honeymoon-Korea-210-PICT2657-Day3-Oedolgae-Jeju-300x200.jpg 300w, https:\/\/www.chekyang.com\/musings\/wp-content\/uploads\/2026\/03\/2006-Honeymoon-Korea-210-PICT2657-Day3-Oedolgae-Jeju-768x511.jpg 768w, https:\/\/www.chekyang.com\/musings\/wp-content\/uploads\/2026\/03\/2006-Honeymoon-Korea-210-PICT2657-Day3-Oedolgae-Jeju-731x486.jpg 731w, https:\/\/www.chekyang.com\/musings\/wp-content\/uploads\/2026\/03\/2006-Honeymoon-Korea-210-PICT2657-Day3-Oedolgae-Jeju-240x160.jpg 240w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><figcaption id=\"caption-attachment-37958\" class=\"wp-caption-text\">From our Dec 2006 trip, and at Oedolgae.<\/figcaption><\/figure>\n<p>So, here&#8217;s what ChatGPT thinks of this Jeju itinerary. Here&#8217;s the copy and pasted version.<\/p>\n<h2 style=\"padding-left: 40px;\" data-start=\"164\" data-end=\"222\">Here\u2019s What ChatGPT Thinks of This 9-Day Jeju Itinerary<\/h2>\n<p style=\"padding-left: 40px;\" data-start=\"224\" data-end=\"586\">Looking at this itinerary as a whole, my overall assessment is that it is <strong data-start=\"298\" data-end=\"407\">logistically efficient, geographically well-structured, and strongly focused on Jeju\u2019s natural landscapes<\/strong>. Rather than trying to cover every attraction on the island, the plan emphasizes scenery, coastlines, volcanic formations, and short hikes \u2014 which is exactly what Jeju does best.<\/p>\n<p style=\"padding-left: 40px;\" data-start=\"588\" data-end=\"809\">One of the strongest design choices in this itinerary is the <strong data-start=\"649\" data-end=\"686\">three-base accommodation strategy<\/strong>. Instead of staying in one place and repeatedly driving across the island, the trip is divided into three logical regions:<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul data-start=\"811\" data-end=\"1038\">\n<li data-start=\"811\" data-end=\"876\">\n<p data-start=\"813\" data-end=\"876\"><strong data-start=\"813\" data-end=\"836\">Seogwipo (Days 1\u20134)<\/strong> for the south coast and Hallasan area<\/p>\n<\/li>\n<li data-start=\"877\" data-end=\"971\">\n<p data-start=\"879\" data-end=\"971\"><strong data-start=\"879\" data-end=\"899\">Seongsan (Day 5)<\/strong> to explore the east side and catch the sunrise at Seongsan Ilchulbong<\/p>\n<\/li>\n<li data-start=\"972\" data-end=\"1038\">\n<p data-start=\"974\" data-end=\"1038\"><strong data-start=\"974\" data-end=\"994\">Aewol (Days 6\u20139)<\/strong> for west Jeju, beaches, and the north coast<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p style=\"padding-left: 40px;\" data-start=\"1040\" data-end=\"1161\">From a logistics perspective, this significantly reduces cross-island driving and keeps most days geographically compact.<\/p>\n<h3 style=\"padding-left: 40px;\" data-start=\"1163\" data-end=\"1179\">Scenic Focus<\/h3>\n<p style=\"padding-left: 40px;\" data-start=\"1181\" data-end=\"1334\">Another thing that stands out is the <strong data-start=\"1218\" data-end=\"1261\">clear emphasis on nature and landscapes<\/strong>. The itinerary prioritizes many of Jeju\u2019s most distinctive environments:<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul data-start=\"1336\" data-end=\"1625\">\n<li data-start=\"1336\" data-end=\"1398\">\n<p data-start=\"1338\" data-end=\"1398\">Waterfalls such as Cheonjiyeon, Jeongbang, and Cheonjeyeon<\/p>\n<\/li>\n<li data-start=\"1399\" data-end=\"1464\">\n<p data-start=\"1401\" data-end=\"1464\">Volcanic coastline formations like Jusangjeolli and Yongmeori<\/p>\n<\/li>\n<li data-start=\"1465\" data-end=\"1516\">\n<p data-start=\"1467\" data-end=\"1516\">Hallasan\u2019s forested slopes and oreum landscapes<\/p>\n<\/li>\n<li data-start=\"1517\" data-end=\"1566\">\n<p data-start=\"1519\" data-end=\"1566\">Coastal viewpoints at Songaksan and Suwolbong<\/p>\n<\/li>\n<li data-start=\"1567\" data-end=\"1625\">\n<p data-start=\"1569\" data-end=\"1625\">Iconic locations like Seongsan Ilchulbong and Seopjikoji<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p style=\"padding-left: 40px;\" data-start=\"1627\" data-end=\"1786\">Instead of filling the schedule with museums or indoor attractions, most days focus on <strong data-start=\"1714\" data-end=\"1785\">short scenic walks, geological features, and dramatic coastal views<\/strong>.<\/p>\n<h3 style=\"padding-left: 40px;\" data-start=\"1788\" data-end=\"1811\">Balanced Daily Pace<\/h3>\n<p style=\"padding-left: 40px;\" data-start=\"1813\" data-end=\"2104\">From a pacing standpoint, the schedule also works well. Most days include <strong data-start=\"1887\" data-end=\"1910\">three to five stops<\/strong>, with enough time allocated at each location to explore without rushing. Average driving time works out to roughly <strong data-start=\"2026\" data-end=\"2051\">1.5\u20132.5 hours per day<\/strong>, which is very reasonable for a Jeju road itinerary.<\/p>\n<p style=\"padding-left: 40px;\" data-start=\"2106\" data-end=\"2312\">The trip also alternates naturally between more active days \u2014 such as the Hallasan hike or the Seongsan sunrise climb \u2014 and easier coastal exploration days, which helps prevent fatigue across the nine days.<\/p>\n<h3 style=\"padding-left: 40px;\" data-start=\"2314\" data-end=\"2348\">Logical Flow Around the Island<\/h3>\n<p style=\"padding-left: 40px;\" data-start=\"2350\" data-end=\"2505\">Geographically, the route also makes sense. The itinerary essentially <strong data-start=\"2420\" data-end=\"2465\">moves around the island in a gradual loop<\/strong>, rather than zigzagging back and forth:<\/p>\n<ol>\n<li style=\"list-style-type: none;\">\n<ol data-start=\"2507\" data-end=\"2820\">\n<li data-start=\"2507\" data-end=\"2555\">\n<p data-start=\"2510\" data-end=\"2555\">Exploring the <strong data-start=\"2524\" data-end=\"2553\">south coast from Seogwipo<\/strong><\/p>\n<\/li>\n<li data-start=\"2556\" data-end=\"2601\">\n<p data-start=\"2559\" data-end=\"2601\">Visiting <strong data-start=\"2568\" data-end=\"2599\">Hallasan and southwest Jeju<\/strong><\/p>\n<\/li>\n<li data-start=\"2602\" data-end=\"2663\">\n<p data-start=\"2605\" data-end=\"2663\">Crossing to the <strong data-start=\"2621\" data-end=\"2661\">northeast for lava tubes and beaches<\/strong><\/p>\n<\/li>\n<li data-start=\"2664\" data-end=\"2712\">\n<p data-start=\"2667\" data-end=\"2712\">Catching sunrise at <strong data-start=\"2687\" data-end=\"2710\">Seongsan Ilchulbong<\/strong><\/p>\n<\/li>\n<li data-start=\"2713\" data-end=\"2769\">\n<p data-start=\"2716\" data-end=\"2769\">Exploring <strong data-start=\"2726\" data-end=\"2767\">west Jeju\u2019s coastal parks and beaches<\/strong><\/p>\n<\/li>\n<li data-start=\"2770\" data-end=\"2820\">\n<p data-start=\"2773\" data-end=\"2820\">Ending around <strong data-start=\"2787\" data-end=\"2820\">Jeju City and the north coast<\/strong><\/p>\n<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n<p style=\"padding-left: 40px;\" data-start=\"2822\" data-end=\"2904\">This approach keeps driving distances manageable and makes each day feel cohesive.<\/p>\n<h3 style=\"padding-left: 40px;\" data-start=\"2906\" data-end=\"2932\">Ending the Trip Gently<\/h3>\n<p style=\"padding-left: 40px;\" data-start=\"2934\" data-end=\"3125\">The final part of the itinerary slows the pace intentionally. After several days of hiking and scenic exploration, the last two days focus more on relaxed coastal walks, viewpoints, and food:<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul data-start=\"3127\" data-end=\"3260\">\n<li data-start=\"3127\" data-end=\"3165\">\n<p data-start=\"3129\" data-end=\"3165\">The Handam Coastal Walk near Aewol<\/p>\n<\/li>\n<li data-start=\"3166\" data-end=\"3194\">\n<p data-start=\"3168\" data-end=\"3194\">Views from Dodubong Peak<\/p>\n<\/li>\n<li data-start=\"3195\" data-end=\"3222\">\n<p data-start=\"3197\" data-end=\"3222\">Beach time at Iho Tewoo<\/p>\n<\/li>\n<li data-start=\"3223\" data-end=\"3260\">\n<p data-start=\"3225\" data-end=\"3260\">Food and shopping at Dongmun Market<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p style=\"padding-left: 40px;\" data-start=\"3262\" data-end=\"3371\">From a travel planning perspective, ending the trip this way helps avoid the feeling of racing to the finish.<\/p>\n<h3 style=\"padding-left: 40px;\" data-start=\"3373\" data-end=\"3392\">Overall Verdict<\/h3>\n<p style=\"padding-left: 40px;\" data-start=\"3394\" data-end=\"3631\">Overall, I would describe this itinerary as <strong data-start=\"3438\" data-end=\"3528\">well-structured, realistic, and optimized for scenery rather than sightseeing overload<\/strong>. It balances driving, walking, and downtime while covering many of Jeju\u2019s most distinctive landscapes.<\/p>\n<p style=\"padding-left: 40px;\" data-start=\"3633\" data-end=\"3836\">In short, this is a thoughtfully designed way to experience Jeju\u2019s volcanic island geography \u2014 one that minimizes unnecessary driving while still capturing the island\u2019s most memorable natural highlights.<\/p>\n<p>These tools are just incredible. How about possible improvements, of things to especially watch out for?<\/p>\n<h3 style=\"padding-left: 40px;\" data-start=\"133\" data-end=\"185\">Possible Adjustments and Things to Be Mindful Of<\/h3>\n<p style=\"padding-left: 40px;\" data-start=\"187\" data-end=\"1275\" data-is-last-node=\"\" data-is-only-node=\"\">Although I consider this itinerary well structured overall, there are a few practical considerations worth keeping in mind. Some locations \u2014 particularly waterfalls, coastal cliffs, and popular viewpoints \u2014 can become busy during peak hours, so arriving slightly earlier or keeping the schedule flexible may help avoid crowds. A few sites, such as Yongmeori Coast, are also <strong data-start=\"561\" data-end=\"579\">tide-dependent<\/strong>, meaning access can change depending on sea conditions, so checking local updates on the day itself is important. Weather is another factor on Jeju: visibility at places like Hallasan or Seongsan Ilchulbong can vary significantly, so maintaining a bit of flexibility in the order of stops can be helpful if conditions shift. In terms of adjustments, I would only suggest small ones \u2014 allowing extra time at particularly scenic locations if the views are good, and being willing to shorten or skip a stop if the day begins to feel rushed. Overall, however, the itinerary already strikes a good balance between structure and flexibility, which is often the key to enjoying a destination like Jeju.<\/p>\n<p data-start=\"187\" data-end=\"1275\" data-is-last-node=\"\" data-is-only-node=\"\">I reckon in a year or two, I should just get ChatGPT to write this blog.
