Actually, Phi Phi is where they filmed The Beach, and not on the island with the hotels, its a seperate island that is very nearby, there are no hotels on this one, the diving is first rate. Here is the beach made famous in "The Beach"
Maybe you can verify this. I could be mistaken, but I believe Phi Phi island is pronounced "pee pee", not "fee fee" as I've heard many news people say. Maybe they are not allowed to say "pee pee" on the air.
