My dad (72) and I (47) did it a year ago. They take you out to a reef about 20 minutes from the ship. The reef is beautiful and the snorkeling is great. BUT!!!---don't expect them to keep a close eye on you! Even though they do have several people in the water on boards. I guess they were looking at the girls, or something, but my Dad took in water and nearly drowned. He made it back to the catamaran on his own where he was helped on board then collapsed into unconsciousness ultimately being evacuated and spending 5 nights in a hospital in Ft. Lauderdale. Do watch out for yourselves!!!
