Chiang Mai

Visit the temples, eat well, shop in the markets and take a commercial and really touristy trek to one of the villages nearby. This will include a mandatory elephant ride and sometimes bamboo boat.

Bangkok

Check the palace and all the city centre (the old area). Get lost in the streets and eat as much as you can as the food is great and the price is even better than the taste.

Phuket

Great spot for relaxing and reaching nearby paradise islands including Phang Na bay where you can paddle your way avoiding the crowds.

Phi Phi Islands

Great for relaxing, diving, snorkeling or simply sunbathing and swimming. Easy to reach from different places by boat.
