Arvada is 14 and hour for adult, i believe 11 for a kid. Longer periods are less per hour.
15$ for an hour adults, kids I think are half. Seriously you'll be exhausted in 30 minutes, and your kids will sleep like newborns. It's fun, and tiring!
I could be wrong but I paid some where around 15$ for 2 hours for my kiddo
