I went to Thailand in November of last year and spent about 5k total for 4 nights in Bangkok and 5 nights in Patong Beach. Airfare was 650 and hotels were about 400 in Bangkok for a 2 bedroom suite split with my friend and 600 in Patong for a room with a hot tub. Plus the flight from Bangkok to Patong(75) and renta car(100)... I spent almost 2 grand on airfare and lodging. So I spent around 3000 on girls, booze, food and souvenirs. So I'd try to budget for 300 a day... better to come home with cash then run out while there... or to have to budget. Everything is cheap there but I wanted to enjoy myself. Going rate for women is about 3000baht for "long time"... about 90 bucks. So with that being a given, I spent about 200 on food and booze a day lol
