Get the kids out surfing ... well sort of. Avalanche Bay Indoor Waterpark has an artificial wave that the kids will love ripping around on. If they're not so much into trying a surfboard, no problem. They can take a boogie board out on the wave.
While they are out trying to hang ten, you can have a seat in front of the wave and get some good action photos. After the photo session, just sit back and enjoy watching the wipeouts.
