The morning after a sleepover, I took Beta, Alpha, and Alpha’s sleeping-over friend Rho to Altitude, an indoor trampoline park. (Fun fact: once upon a time they were called “jumpolines” until your mom got on one.)
They have a field of unadulterated trampolines for jumping, plus dodgeball (on trampolines), basketball layups (on trampolines), long jumps with trampolines (landing in a foam pit), climbing walls (over foam pits), and pugil sticks on a balance beam (again, falling into foam pits).
It’s pricey, as you’re charged by the half-hour and it’s $9 per person per half-hour (discounts apply for longer blocks of time). You also must bring special Altitude-branded non-skid socks or buy them for $2/pair.
It’s a really good time despite the price. I recommend not more than an hour at a time – the kids really started to flag after about 45 minutes. They slept well that night, too.
