Complaint Review: Avalanche Bay Water Park

I booked a two day waterpark adventure for my kids- two months in advance, from the Avalanche Bay website, payed up-front.  When we arrived, we were told that we had to pay another $80 for waterpark tickets.  When I asked to speak to the manager, I got the run-around.  After speaking with three different people, who all alleged that they were the manager, I was told that they weren't going to do anything for me.  I asked to cancel the reservation so that I could take my kids to a different waterpark.  They told me that I would have to pay a $200 cancellation fee.
