I am 24 and planning a trip with my wife to Thailand for around 8 days. What would be the best route to take to see the country? I thought about arriving in Bangkok and staying about 3-4 days then taking flight/overnight train to Chang Mai for a couple days. Should we then try to fly down to Phuket to see the southern part? We are trying to stay on a budget and not spend too much $$, anyone have any tips of an itenerary to take?
