Our family was at Sea World and Discovery Cove this week in Orlando. It was chilly in the 50s - some of the roller coasters were actually down in the morning until the sun heated things up a bit. Our day in Discovery Cove was fortunately the warmest of the week. The water in the lazy river is heated to 85 degrees, so we didn't notice the cold until it was time to get out (or run to the snack shop or bathroom).

Here are some clips of us snorkeling. Video and photos were taken with my oldish Canon Powershot A510 in a DiCAPac waterproof case my wife got me for Christmas. Stayed bone dry! In a couple of shots you can see the lens cover making a black edge, but other than that it worked great.
