Great trip report! It was fun reading it and reliving our recent visit there. The Aquarium is my all-time favorite dive spot...anywhere. I looked back in my dive log and over the years I wrote the same thing....OMG, I LOVE it here! It was at the Aquarium I saw the largest loggerhead turtle I've ever seen. It looked like a Volkswagen gliding along beside me.
As for your mention of mosquitoes and noseeums, we have never had a problem with either, but we stay in town at the Palms, although we have been all over the island. DH is usually a bug magnet, too. Hmmmmm....
