I feel really bizarre asking this, but I've learned quickly that there truly are no stupid questions among this great group of people, so here goes:

My family (Mom, Dad, brother and me) is planning a WDW trip to celebrate Mom and Dad's 50th Anniversary in 2009. My brother is a certified diver, and my Mother thought that she'd heard of some sort of special day when divers can do their thing in the Living Seas tank. This strikes me as unlikely, but I figured if any group could get to the truth about this this is the group! Does this ring a bell with anybody?
