It seems like Golfland/Sunsplash has been around forever, and there's good reason why! It's a great place to cool off for adults and kids alike. They have a mix of exciting slides, as well as gentle floating tube rides. The Golfland part of the area is a popular place to go mini golfing, especially when the sun goes down.
Plus, who wouldn't want to have fun and putt/splash around in the place featured in Bill and Ted's Excellent Adventure? : )
