Hi again
Always book when you are in Patong in one of the salesbooths that is everywhere, its cheaper and you can hassle about the price. Many times they will offer free transport but if you book with the hotel touragent, they will charge you for transport also.
My suggestion is James Bond Island with a visit on the way to the Monkeytemple and lunch at the muslimvillage in the middle of the sea (build on stillts).
Also dont miss Phuket Fantasea. A little expensive (1,300 thb) but the show is worth it. Dont buy dinner with the show. Too expensive unless you can eat like a mad man.
I think a trip to Phi Phi is too far and too many hours compaired to you only have ... was it 5 days in Patong ? The Phi Phi trip is also a little boring.
If you want a quiet nice beach, then try Laem Singh. About 20 min from Patong. Motorbike 150 thb per day.
Elephantride is good down at Chalong. Great views from there.
Simon´s Cabaret is good fun and not too expensive (about 500-600 thb) . Go check out the katoyes, they are unbelieveable.
If you are in Kata, dont miss the Dino Park minigolf. Play when its dark.
