Katsc4,
there are lots of hotels on the island, and the //ambergriscaye.com/conchshell/ looks like a good choice for April. I've never stayed there, myself, but I've hung out with people who stayed there and liked it. I don't think that they have airconditioning in the rooms-that shouldn't be an issue in April.
My recommendation? Book it and stay the night. Be sure to tell us how you like the place.
Dan
