When did Fun Mountain stop being a family friendly establishment?

Summer is almost at an end, and I'm really hoping to get a trip to Fun Mountain in before it starts getting cold.

I went to their website to check out their hours and am glad I did. I don't want to be taking my 3 year old daughter to XXX DAY at the waterslides!!!

What the heck is going ON at this park, anyway?!?!
Here's a link to the website where I found this graphic:

Proudly in my sixth Cola free year!
