I had booked a birthday for my sons 17th birthday. We had an amazing time. I was not sure what to expect and was worried that we would not have enough especially since there were men and older teens in the party that devour food the size of mountains. Before our last race we had ordered extra nachos and they were waiting for us in our private room. They had a tv that was connected to Youtube and my son was playing his faves.The thing that surprised me the most is what they did for my sister. My sister is recovering from a torn hamstring surgery. She felt that she would be able to work the pedals since it had been months since the surgery. Once they saw that she was in a wheel chair they nicely asked if she was driving and if she would be able to work the pedals. When she said that she hopes they did not hesitate to give her a cart that had hand pedals. This was distressing to my family since we were left in her dust on the track.I would definitely do this again. My family had a great time. Everyone said that it felt like we were in a video game only without a weapon arsenal.

Great time, friendly staff, helpful, kind. My only complaint was it was very hot in side, no air conditioning. Two very big fans that had no water in them, just blowing hot air. Other than that we had fun.

We went early around 11:20am, it took about an hour for 3 races for myself and my 10 YO who had to race separately. Only 4 stars due to the large difference in performance between the karts. 1st and 3rd carts were slow (last was 17). Middle cart was quicker (42). I actually prefer this location to Las Vegas and Orlando.

Great experience! The employees were all nice and accommodating. I've gone to other ones for the employees are a little arrogant or they have some type of power Trip, that is not the case here. Food, beer good. Plenty of parking, not crowded on Sat night.
