As someone that's traveled a fair amount it doesn't really take all that much planning to travel. Buy a ticket, book a hotel, show up. Like many things it seems scary at first but once you've done it a few times it turns out it's pretty easy and it gets easier all the time.
Thailand, at least Bangkok, has public transportation. Now-a-days you likely have a smartphone. If it's unlocked, get a sim at the airport for < $20 usually. You can find your way all over much more trivially in 2022 than 2002 or 1982 etc... Take cabs or use Grab if you want. I haven't used Grab in Thailand but I did in Kuala Lumpur and it made getting around so trivial (also used public transportation in Kuala Lumpur which is pretty good too)
Thailand in particular is also relatively cheap. No idea what flights cost right now but high-end hotels can be as cheap as $120-$150 a night and that's top end. Plenty of places for $25 a night. (vs say SF, NYC, London where low-end is $350 a night)
