I've tried several times to bid for Phuket and never succeeded. My observations are: - Phuket zones are spread quite widely and you could end up far from the beach or populated areas. Or, if that's what you WANT, you could end up IN the populated areas or on the beach. - Like Bangkok, there is little savings, if any, from using Priceline. I've found the prices on sites like Travelocity and Orbitz are at Priceline "name your own price" levels. - Hotel quality varies DRAMATICALLY in Thailand and you need to be very very sure of what you are getting in advance. My strategy for Thailand: - Find a star quality in your price range in the place you want. - Research the property on hotel review websites like this one and TripAdvisor. - Book the lowest price via the hotel website or other search engine. Priceline is perfect for cities like London, Paris, New York, DC, etc. and I use it all the time with incredible savings and almost always great locations and quality. For the little or no savings, and the huge unknowns on Priceline, I have never seen Priceline worthwhile for Thailand.
