Crystal Springs Water Park / Bathrooms needed attention

The place is filthy. They don't clean up. I complained numerous times that the bathrooms needed attention. It took Multiple times for me to get someone to go in to clean it up. I was told by a snippy little lifeguard that they don't pay enough to clean. I also spoke to the manager mr. Gerhardt. He stated that they always clean and that was just a one time thing. I went again to there and it wasn't any better.What can I do besides not going there? Can you help me?
