Bounce-around kids night out Friday nights at Ann Arbor's Xtreme Bounce

What's a parent to do?
I just heard about the Kidz Night Out at Xtreme Bounce (82 Aprill Drive, Ann Arbor 48103) in Ann Arbor. Every Friday evening from 7-10 p.m., parents can drop children ages 6 and up for a night of bouncing and pizza for only $10! Not too shabby when a sitter would cost me at least $5/hour.
Now my dilemma is how to get my 4year old to pass for a 6 year old so that we could drop both kids and run away for a few hours.
Do you have other solutions for kids while mom and dad get to go out? If so feel free to pass along the ideas!
