Tell us when and for how long. You get a day-by-day route that respects the drier coast, the real transfer hours and your pace, and that you can change on the spot with the consequences shown.
The most common first draft is a stop every two nights. The planner's job is to say what it costs, and to show the smaller change that keeps the point.
What you give up: Pai and Koh Lanta. Both are still one tap away in the planner, and it will tell you, in hours and nights, what adding either back costs. Already have a route sketched? The route check runs the same tests on it →
Every one opens in the planner as an editable plan. Change a stop, a night or an answer and it rebuilds, with the consequences shown.
The constraint: a six-year-old. The planner drops Pai, holds back climbing, ridge paths, the night swim and the rooftop bars until you've checked with the operator, and prices two rooms and four fares, with the assumptions written down.
Open the family plan → Two of you · July · divingThe constraint: July. The Similan and Surin parks on the Andaman side are closed for the season, so the diving goes to Koh Tao, in the Gulf's shoulder months rather than the Andaman's monsoon, with a flight to Samui instead of the ten-hour night train the old route defaulted to.
Open the diving plan → Solo · February · sleeper trainsThe constraint: money and a taste for trains. The sleeper replaces a hotel night and a $45 flight, the reality check counts its 13 hours as overnight rather than a day to protect, and early February clears the burning-season cut-off the planner applies from mid-month.
Open the sleeper plan →A row is checked when we've read it on the operator's or the authority's own page and written down the date. When we haven't, the planner says so, in amber, on the plan.
Not daily, and not twice a day. Our own planner said "a daily parade" and our kids guide said "twice-daily" until an outside review caught it. Both were corrected the same day.
The planner's 2026 dates were re-checked against the published Haad Rin Business Association schedule on 22 August 2026; 2027 dates are projections and are labelled as such on every plan. That schedule itself warns the 27 October party may move.
Lines like that print above every verdict: no dates yet, children's ages not given, a transfer composed from two legs we checked separately rather than one we've ridden as a through-route. The planner never prints a green light while one of those is open.
Who maintains this. Thaitinerary is written and maintained by one person, Nishan, with no staff and no sponsors. Rows come from operators' and authorities' own pages, checked and dated, plus time in Thailand; the next visit is this autumn, and what it changes gets logged on the page it changes. Partner links earn a commission at no cost to you, are labeled where they appear, and never decide a pick.
The planner is free and stays free. The Companion is help carrying out one trip, for the whole party, and it ships with the full planner in late October 2026.
Save your plan against an email if you want it kept: one email at launch with its link, nothing else.
What it isn't: live fare tracking, rebooking, unlimited human help, loyalty optimisation. One trip, the whole party, no subscription, revisions to that trip included.
Founding members, anyone on the list before launch, get the Companion free for good, including the pre-departure re-check we promised them. That promise stands as made.
Where to go for your dates, how long the route really takes, and what the headlines mean for a tourist's actual route.
Bangkok, Chiang Mai, and six island nights on whichever coast is dry for your dates. The realistic route, with real transport and real costs.
