Great experience, our family really enjoyed it, especially feeding the giraffes. In addition to the drive-through there is also a walk-through safari with animatronic dinosaurs.
You have to call to reserve the appt and use your Groupon and it took several phone calls and voice mails before I finally reached someone (no one ever returned my voicemail messages) but the overall experience is fun.
One thing to note, there is no air conditioning in there so it gets hot, especially with the coveralls, gloves and face mask on a very hot summer day. We had 4 people and got 30 minutes which was more than enough time, especially with the heat. They had 3 decent size bins of mostly glasses and plates to break, and 3 monitors / 2 keyboards but could have been a bit more as we finished it all and then picked up some stuff out of the broken pile on the floor to use. Overall, it definitely gets some rage out and we would all do it again. We will try the paint room next!
