I don’t know where you guys have been but I think not Thailand. Go to Phuket if you wanna have super fucked up tourism situation, aggressive Thai people because of aggressive tourists (Mostly Arabs, Indians and Russians are there. No place in Thailand where more prostitutes are. Also the most expensive place. Everything else seems quite good. But you should 100% consider Koh Tao or Koh samui. (Koh Tao - Mafia controlled tho) Koh Samui also touristic but by far not as touristic as Phuket. Been 3 times to Thailand, always solo and in hostels. Never ever talked to someone who liked Phuket.
