The most fun workout. No doubt it's packed with screaming kids all weekend, but there's plenty for adults, too. Free jump area, dodgeball court, foam pit, and even weekly aerobics classes! It's a little expensive- $12 for 30 minutes, $15 for an hour, $13 for a 60-minute class- and it's a little far out there, but we got to act like kids and workout without realizing it (until the next day!). Definitely worth it!
