We have been there twice this season already - Once the water park was closed for some undisclosed reason and the second time we found out that the park is open to anyone who wants to use it not just campers.
It was a turn off to us because it caused a large portion of the overcrowding you mentioned. Not sure if we will be going back yet or not.
