I bought a Groupon for my son's birthday, which includes 4 races (which cannot be shared or used on the same day-that means 4 separate visits). Also the membership included with the Groupon does not qualify him for the free birthday tshirt or free race even though I brought him in ON his birthday...they say that they said that on the coupon, which they DIDN'T. Also, I was not able to get the member price for a race for my other son, because the membership is in my other son's name. Had to pay full price. Employee was rude, sarcastic, and condescending. The ONLY reason I am giving it 2 stars and not 1 is because my boys had fun. I was not aware of the scary "safety" conditions til I read another review, and now I'm a little leary of my kids riding the not well-maintained go karts!:(
