Caribbean - Condo or Suite for 6 w/ Snorkeling

Planning a trip to the Caribbean for January with both kids and their significant others. So, we are looking for good accomodations for 6. Optimum would be someplace with great snorkeling directly off the resort -- so that we could get in the water, swim out to a reef, and snorkel to our hearts content. Kids might want to take a resort dive course as well.

Considering various options, including Grand Cayman condos (or 2 rooms at Westin), Ambergris Caye (although flights are much more costly to there), Grace Bay in T&C, etc.

Any suggestions are welcome. Thanks.

If you are considering the TCI, Coral Gardens and Windsong would be suitable condo's, with a reef off the beach or a short walk to Smith's Reef (better snorkeling), lots of other hotel type accom.

Might look at Aruba or Bonaire. The resorts cater to the diving set.
