Never done a big international vacation. My wife and I have saved 3 years for this. We are going to live like rock stars. Tell me you tips, tricks, suggestions ect for 1. international travel and 2. Thailand related.

17 days is what we are have booked. Also airfare in Thailand is CHEAP so we will fly from Bangkok where our flight lands to Chang mai for the temples and scenery, then Pei Pei for some beach action, and lastly back to Bangkok to explore the big city. Are we missing anything?

We chose Pei Pei because it is 1/3 the price of everything of Phuket and WAY less touristy.
