KarenNY - PADI is a Scuba diving certification agencey (PADI = Professional Association of Dive Instructors).
Fam4jc - I've never done a dive at WDW, but I think I saw something about diving at WDW on these boards. If you find anything out, please post. (I'm a diver too, SSI certified not PADI, but still a diver)
