Been meaning to bring this up... at first I thought there would be no pond/lake because they never poured concrete for one... and then I noticed the IOA lagoon APPEARS to be just a natural dirt bottomed lake and my question being is this a Florida thing? Is this just a Universal thing? Does Disney put concrete bottoms to their water features in Florida like they do at Disneyland? The idea of that natural dirty water and all the bugs it invites makes me nauseous lol
