Unfortunately Epcot is the only dive I've taken in American waters. I was certified in Malta because my in-laws live there and we are there for a few weeks at a time when we visit(needed something to get away from them a few hours a day). Diving is really cool there because of all the shipwrecks from the war, you can shore dive a lot of them. I would love to do some diving down there but since DW and DS are always with me and she doesn't dive it's kind of tough to break away when we are on vacation. DS takes swim lessons at a dive center and their program gradually transitions into snorkeling then diving so eventually I'll have a dive buddy.
