Naturist island

We have left the camaraderie of the cruise ship for a “couple’s only” hotel on the north coast of Jamaica, which has its own naturist island where you can sunbathe and swim.
I am not quite sure how we ended up here since neither of us has the slightest intention of swimming starkers’ even from an island.  
 
It is now becoming clear that this is the reason people flock here. The hotel itself is small, comfortable and has known better days.
Ten of us from the cruise ship have checked in and I doubt if any of us, all in possession of bus passes, will be swimming in the nude.
 

I guess we didn’t read the small print.
