Thanks for the great advice. I am unsure if we should buy snorkel gear here in Edmonton or just rent it down there. We do plan to snorkel in Cozumel and Grand Cayman.. any advice?
Also I have heard that it is cheaper to book excursions outside of Carnival, but that the tenders for Grand Cayman are done on a priority for the Stingray city booked through the ship.
Any advice on the above?
