Ok, Ive been trying to talk the GF and her daughter into going to the Grand Prix so we could race the cars for the past few months and I finally talked them into it and I think it was only because our friends 7yr old asked if she could go.
Buy the $20 1 hour pass and just start going nuts. I blinked and the hour was done so be prepared to go back and buy another hour.
The pizza was a surprisingly good thin crust and they had a daily special that filled me up for $5.75.
Im 5'11 and 215lbs and had a hard time getting in and out of a few of the rides/cars but the 7yr old and all The other kids were able to climb in and out with no issues.
We didnt try the big track this trip but we had such a good time and the grown ups are so competitive we will be back to race the big cars.
