It'll basically be tropical forest in between.  I'm not sure the technical term, but if you saw the Duct Tape Island episode of Mythbusters, basically what I'm imagining.  Granted, that was a Hawaiian island, but it works.<br/><br/>I'm not planning on a city built up on the island or anything like that, though, since the ferry can always take people to the mainland (about an hour trip) which is much more built up.  The hotel wants to keep that forest mostly undisturbed so that the guests can be at one with nature and all such.
