Urban Air offers a $49 play pass at no cost for National Adventure Day, today only

Urban Air Adventure Park is marking National Adventure Day by loading an Unlimited Play Pass worth up to $49 onto accounts at no cost through participating U.S. locations, according to Hip2Save. Families need to download the KidHub app and register an account by 11:59 p.m. local time on October 9 to qualify; existing KidHub members don't need to re-register, since the pass loads automatically to their account.

Passes started loading at 6 a.m. CT on October 9, with a confirmation email following from Urban Air, so it's worth checking both your inbox and spam folder. The pass is valid for 45 days from open to close on whichever day you choose to visit, and the offer is limited to one pass per KidHub account. Urban Air grip socks aren't included, so bring a pair from a past visit or plan to buy them at the park.
