Great Barrier Reef
Looking forward to our visit to the Great Barrier Reef, but not quite sure what's involved. It appears that scuba diving is an option ($$) and snorkeling is included if you want to do that. Can anyone explain to me what happens on the visit to the Great Barrier Reef?
Does everyone go out on the catamaran? Do the folks going snorkeling and scuba diving go out on this catamaran? or some other boat?
Does the usual catamaran have a glass bottom? Do most folks go snorkeling or scuba diving - or just a few?
Clothes - obviously a swim suit would be helpful. Does one show up at the boat already swim-suited? Any other clothing recommended? How about water shoes? Are towels provided.
Would love to hear from folks who have gone out to the reef on their experience. Anything you didn't do or bring that you wish you did?
Thanks!
