Our first cruise, back in 1995, we signed up for a snorkel excursion in our first port, which was Freeport, Bahamas. We had never snorkeled before so we used the excursion supplied equipment. After snorkeling, we watched their method of "sanitizing" the equipment and decided we would never use "shared equipment" again. We went to a sporting goods store and bought complete sets for us and the boys before our next cruise. Joey, it was relatively inexpensive. Back then, they did not charge for extra baggage on airlines, so we always took a suitcase that had nothing but snorkel gear in it. As I prefer to drive to port nowadays, it is not an issue either, so we always carry our own. Our friends, who cruised with us for the first time last Nov., asked us this same question when they were here last summer, and after they heard our answer, we all headed to Sports Authority and they bought their own. They were on sale for 1/2 price and I think they paid around $30 per set.
