Well, I was trying to make an itinerary but I got busy with school!! If I remember correctly, we'd land in Bangkok and spend the day there. For day 2 and 3 would be Chiang Mai. Day 4 and 5 we want to go to Phuket. Day 6 and 7 we want to visit Vietnam. We will have only 7 days because my friend is a teacher and needs to be back by January 3rd!
I have been looking up tourist things to do while we are there. However, the itinerary isn't set in stone because I never researched the locations to see if all the things are possible and in similar locations. :D
