Travel advice

Not really a good period, uh? God bless the people in troubles in your country anyway. Are you still looking for travelling to Thaialnd in February? Well, 5-6 days is not much, but enough to enjoy some good time. Phuket is not that small, depends what are you looking for from this vacation. I guess you have enough beautiful beaches in Indonesia as well, so I don`t think you are much into marine life. If you are looking for nightlife than stay in Patong, plenty of cheap accommodations. Kata is even a better choice, as Patong is the hell on earth. They are all busy areas anyway. If you would like to be closer to nature for a more real spot of Phuket than chose Nai Harn or Rawai area (I live here).  Once at the airport take a public cab on the right hand side or a sharing mini-bus to these destination. If you are travelling on budget, than just drop off and look for the one you like. Than rent a motorbike, it`s pretty cheap, get a map and drive yourself to the Big Bhudda, Wat Chalong and Phuket Town, very nice sino-portuguese city with many chinese and bhuddist temples. If you have time drive up to Bang Pae waterfalls and Gibbon`s rehabilitation centre. 2 days in Phuket are too short to do anything. If you want to see surrounding islands, go to Rawai and take a long tail boat to Coral Island or Koh Bon. You also want to visit Krabi, so you don`t have to visit the Phang Nga bay, pretty similar scenery as Krabi. Krabi also has lot of cheap accommodation, rent a motorbike there too and visit Ao Nong bay. Trip to Phi Phi not really worth, packed of tourists, you`ll be disappointed in that period. By the way, be sure that your visit is not the same period as Chinese New Year, `cause it will be very very crowded.
Take care and good luck!
