They should have a sign that explains that they don't accept American Express.I waited in line at the concession stand for 20 minutes, the lady at the desk tells me that she sometimes doesn't accept American Express.I asked her could I come back with a different card,and she said yes.I come back to the pick up line.The other lady is saying I have to come back and wait in line.I tell her what happen and she even asks the other girl can she take my order.She just said for me to come back in line.I am pregnant and the line was longer than it was the first time I was in it.Thank goodness I had crackers in my bag. I think it is ridiculous to make a customer come back in line when there is no sign that states that they don't accept American Express.The water park it self was overall a fun experience for the family, but I probably would not come back to order food unless I have cash because I'm not taking a chance that they tell me to wait back in line. read more
