Went there today after the Sea Quest Aquarium. I have a 7 and 4 year old. I purchased two go cart rides for $20; no food. Unfortunately, the cashier did not tell me that the 7 year old had to be 51 inches AND 9 years old. There are only signs at the go carts that say height restrictions not age also. One of the employees at the go carts was not friendly or helpful at all when I said that no one told us the age restrictions and whether or not we could get our money back. We did mini gold instead which, was cool and the kids loved the atmosphere.
I would recommend some signage about the age restriction. Also, I probably would not go there again just because the limited options of activities for younger kids.
