We did a snuba package in Aruba, myself and my 17 yr old daughter and her buddy. It was a blast. Took us out on a HUGE catamaran, stopped three different snorkling spots and the snuba people were taken for their dive for about 45 minutes each about 6 at a time. It is just like scuba except your regulator is attached to a long hose (you go down about 20 feet) for breathing, no tanks on your back. The girls had a blast, I was a bit nervous so when they took all the snuba-ers the dive intstructor grabbed me and took me again solo. It was great. Then back to the boat for a fabulous buffet lunch and open bar. Probably about 4 hours total. I highly recommend it to anyone. There were about 50 people on the boat and maybe 15-20 actually did the snuba thing, the rest just snorkled.
