I have just returned from Phuket. and trust me it's way beautiful than most of us have imagined. it's a very relaxed beach town. the best way to explore Phuket is by hiring a two wheeler, which would cost approx 250/- THai Bhatt per day. they may either take cash upto 5000/- TBH as security of your Passport. Remember to take pic of teh vehicle in front of them, so they might try and extract money from you from getting it damaged (this is what I had read from people, but, I did not experience any such thing) 1. Big Buddha
2. Karon Beach (enroute on way back from Big Buddha)
3. Simone Cabret (also can be done on the way back from Big Buddha, book it prior)
4. walking Street at night
5. Patong Beach
6. Night clubs ( mostly have free entry: illuzions, seduction, Hollywood are amongst the top)
7. do try the foot massage and thai massage.
Also, don't forget to visit the Islands by Boat. I would suggest and recommend Speed Boat, instead of the long tail boats. helps save a lot of time. and better experience. if you are there for more than 3 days, you can do both Phi Phi and James Bond and if only 3, days then my suggestion would be James Bond island.
