Staff needs better training, my wife daughter and I was charged $30 to ride the go carts when it should've been $15, we told the young employee that we had a membership and it should be a partial discount, his reaction was no sir no discount for go carts, my wife read the fine print on the membership when we got home and it says discount $ 5 each party with membership total $15 for 3 people, and that left my family and I very disappointed.
