Hello everyone! I have a questions about the fins you can rent at Castaway Cay. Are they the ones with the adjustable straps and if so has anyone had a problem with them irritating your feet? I keep going between renting snorkel equipment and purchasing my own. I realize it's a drag having to pack and carry your own equipment but on the other hand I don't like the idea of putting a snorkel in my mouth that been in someone else's mouth. I hope that doesn't sound rude. I don't even like sharing drinks with my own children. I figure that there must be some sort of cleaning process that they folllow on all the equipment but it still makes me alittle stand-offish.
