No?
I'm not excusing the park, it's not good enough.
But history points to this day never being good for the park. To expect it to be dramatically different is living in false hope in my opinion.
I question yours and anyone else's judgement who invested so much time into visiting today. That's not my being rude, just honest.
By all means formally complain to the park, seek compensation, or whatever. Tell the park you had a bad day, and vote with your feet and don't return on an opening day. It's the only way they'll take notice and try and make improvements.
