My daughter worked in the outside bar there last summer,(she's applied again for this summer). I'm surprised you are going in May, as the place is a complete shambles with alterations going on. They have funny "pyramids" at reception and a beautiful (but I suspect) a highly dangerous decking round the pool. There are a few shops and restaurants there, otherwise you have to catch the local tib bus to San An or the ferry (daughter's sometime boyfriend runs that). I think it's generally a nice place and the staff are very nice. Do check that it will be ready and open.
