Well what do you mean by ready? Phi Phi is open for business and needs all the tourism it can get. There are gaps were structures used to stand but I hear the beach's are even nicer since the Tsunami.
I'll be heading down in a few weeks to help out where I can and also enjoy the beautiful island.
www.hiphiphi.com for a list of open businesses and also a very good message board.
