Came 2 days in a row. Kids mostly had a lot of fun, however at one point my daughter got a little rattled at how aggressive some of the drivers were and decided not to race anymore. Son had a lot of fun. Facilities were great. We did the walk-in so there was 60-90 minutes wait. Probably better to purchase in advance with the higher premium but less wait. Staff were friendly. Tried doing registration online but they could not see it in their system (maybe I chose the wrong location?) so better to do registration on their kiosks to avoid that issue. No way to check account online for number of races left, but apparently they are working on this.

Great race and place...but I don't understand why I couldn't buy the 3 race pack to save some money and split it between two racers

This is a great place to get your race fix. Dad, mom and the kids (as long as they are at least 48” tall) can all drive a car. We’ve even booked a corporate event for a business party and it was a great time. All the staff wants to know when we’re doing it again.

First timers. Brought my son to practice driving B4 taking his DMV Permit Test. It really helped. For real though this is definitely a fun family experience. See you guys again soon. bpeddie 🤜🏾🤛🏼

Killer time, but the consensus in our group was that not all karts are created equal. These are electric, so maybe it comes down to the charge time. If that’s a concern to you, maybe look into one of their gas powered locations.Came at 5 on a Wednesday and had the place practically to ourselves.

My nephews loved it. Bought a beer and it wasn't cold enough and it's very hot inside in the summer so be prepared.

Second time here and this place is nice. The facility is clean, people are nice and the wait time is very minimal, at least the first time I went. Last Saturday, I got there at 10AM, when they opened and no wait.
