i am from the UK..where do you get your visa from? so you can't travel a full 90 days, you need to do a visa run? is this quite straight forward? sorry i'm quite new to all this!

no you cant do a full 90 days (i would love that), u have to do a visa run. they can be simple or they can be really long and annoyying - iv done many visa runs in thailand the cheapest ones i find are the boat trips to malaysia, bookable everywhere in thailand but it takes so long and its soo boring!
i find the best visa runs i have done have been me leaving thailand and going on a weeks holiday to somewhere such as cambodia however the burma visa run aint bad either, you can do it on foot and takes a few minutes, if you around up north that is
