Your first 2 points were spot on, the last one, I have a problem with. My wife and I have been there 4 times in the past 3 years…three times in December (including this past December) and in May 2021.
I don’t know if we’re going in the “clean” time of the year or what you’re finding filthy, but the parks and Boardwalk/Beach Club were clean and orderly. The ONLY restroom that was messy was the one across from Dinosaur in AK and there was a cleaning CM inside sweeping up and wiping down the sinks. As a matter of fact, there were CM’s near or in a majority of the restrooms (especially the busier ones). I’d really like someone who’s there to provide date stamped photos, not stock pix from Google. I’m NOT a pixie duster by a long shot, but the parks were clean the times we were there. I live 20 minutes from Six Flags in NJ…trust me, there’s NO comparison.
