I looked at it after you mentioned it. Looks fun. Of course, I wouldn't mind the buffet & open bar part.
One of our favorite excursions is Captain Bob's speed boat & snorkel trip on St. Martin. Fast boat (I think his boats are custom and he just adds engines). They fly. But it also involves snorkeling, beach, lunch, drinks onboard, a stop at Maho to see the planes, etc. We're doing it for the 2nd time in March, 7 years after the first time.
I have to find stuff like that so that it appeals to both me and my wife. She's big on snorkeling but doesn't really drink. I can snorkel for a little bit then I get bored. So this has a bit of everything. I can go back to the boat for a beer while she snorkels some more.
