I had planned on visiting Thailand from Dec 28th to Jan 16th, ~3 weeks. I've read that's peak of the peak season so the prices shoot way up. I'm currently budgeting about 70 USD/2090 baht a day and 500 USD for flights inside Thailand (~2000USD total). I don't think I'll spend much time in south Thailand, maybe 4 days in the Krabi area. Mostly north Thailand and Bangkok. As far as room I just require hot water and a private room (so hostels are out). Will that be enough and if not what do you think would be a good range? Should I check out Vietnam or Loas instead?
