I pack a seperate bag of dive gear for me and my wife. It includes masks, snorkels, fins, booties and a life jacket (my wife is not the world's best swimmer) for snorkeling. I know my gear fits and I am used to it. I also bring dive lights, my dive computer and wet suit for scuba. We snorkel w/o the need to rent anything and I rent a bc, regs, tanks and weights for scuba. This seems to work out real well. My buddies like to bring there own BC and regs because they're used to them.

AC is a snorkeling/diving destination, so I would assume you'll be spending alot of time using your snorkeling gear. I would suggest bringing your own.

my $0.02

Good luck - I'm sure you're gonna have fun either way.

Cheers!
