Thanks for the responses.

Yeah, I would hate to go there and not be able to go to any of the neighbouring islands, and have to sit in one place (mind you, that's not the worst fate, but this is quite an expensive trip, so I'd rather make the most of it).

As for other Thai islands - can anyone suggest really beautiful locations? Somewhere hopefully not too overdeveloped, with beautiful scenery.

I found this page from the Phi Phi Island Village resort which has absolutely stunning pictures of Koh Phi Phi. This is exactly the kind of destination I am looking for:

I'm going to review the posts at travelforum.org that you suggested, dcadude, thanks. Do you (or anyone) know of a site to see photos of other Thai islands that might be candidates for a visit?

Btw, this web site has some tsunami aftermath photos, from Phuket and a few from Phi Phi, in two albums:

Thank you!
