sorry, forgot to add, I'm from UK, and looking for the easiest way to stay in Thailand for around 40/ 45 days, re visas
it seams I've been misinformed re a 60 day tourist visa. thanks in advance
TLDR : Answer Summary
As a UK citizen, you can enter Thailand without a visa and receive a 60-day stamp upon arrival. It's essential to have proof of accommodation and an outbound flight to present, though proof of sufficient funds may not be frequently asked for. If you wish to stay longer than 60 days, you would need to obtain a visa in advance.
