We just got back from our Caribbean cruise and we booked that same snorkel tour in Barbados. My family is all snorkelers, but there were some divers on our boat, so they do combine divers and snorkelers. The crew on the boat were awesome and really made the day fun. Thanks Red and Roger, you guys are awesome!
We planned to go to Barbados last year, but we ran into some trouble with the dive company we made arrangements with. I don't know what the fuss was really about (I was not the one who contacted them) but it got my friend very pissed because the dive company (which I'm not going to name) made some changes a day before our trip. Well, that's the story I know.
