We bought a summer pass for a discount at Urban Air to go along with our free passes we got opening day. Anyway. There are two passes to add five kids to a birthday party for free. We will not use these before they expire on 8/14 so if anyone wants them let me know. I have a friend who might be using one if they allow the pass for a future birthday party (8/25) if they pay in advance. Also it is a really good deal on the summer pass if you have kids

Update we still have these passes if anyone has a party in the next two weeks to add five more people for free
