JJ Extreme was VERY disappointing!!! I will never go back. For the money we paid, more than half of the play structures, games, and rooms did NOT work! The Xbox did not work, one of the Wii systems didn't work, then they had other games that were broken, the nerf dart room had two nerf guns that were broke (we had 14 kids for the party) and I even asked the lady at the front desk to get more...she could care less. We didn't get the drinks we reserved and were pushed out of the room ("sorry your time is up, everyone needs to leave now"). Very maddening and embarassing to our party guests.
