Not a good activity for kids 6 - 7 years old.  This is primarily due to the fact that kids under 8 are not permitted to participate in dodgeball or play on the main trampolines without a chaperone.  We brought our son who is 7 1/2 and his friend who is 7.  Basically their only choices were to play in the 'little kids' are (where they had to avoid jumping on very small children) - or - stand in a long line, jump into a foam pit and get out.  One other attraction was closed, so I'm not sure what ages were permitted in that area.  Probably won't go back even when our son turns 8.
