We feel the same way!
After our first WDW trip, we went to Knoebel's here in PA a month later. Free entry because we support our public television station.
Even with free entry we walked around grumbling. We only stayed about 4 hours. Compare that to the previous years PBS day at Knoebel's, when we stayed from opening till 7pm and had a pretty good time.
After going to WDW, I think we just noticed the surroundings more.
Later that summer, while visiting family in Texas, we took the kids to Six Flags over Texas. I was feeling all nostalgic, since that is where we went as kids. I wanted my kids to feel the same.
Just didn't happen! First, the price. For four tickets, 3A and 1C it was nearly $200!
Then going through security, they wanted me to throw away my 2 year olds juice and dump out her milk sippy cup!!!!!!
I pretended to do it while the guard was checking my mom's bag, but kept it in my backpack. Who in the world would spend a 102 degree day at a theme park giving their toddler sodas from a stand?????? Not me!
Then, it was 102 degrees. Not the parks fault, but the fans they have mounted on buildings and in queues were not running! I thought we were all going to pass out from heat stroke.
The park was filthy, bathrooms horrid, and the staff even worse.
They have that stupid Q-bot thing you pay for if you want to skip the line, which just seemed too complicated.
The backstage areas were in no way hidden.....
Should I go on?
The whole time we were all grumbling and saying, "this just isn't Disney".
We left after just a couple of hours.
I will never go back to a Six Flags again (the one in NJ is just as bad).
