The park will finish the lines for rides at 6 and clear the park. So yes, they really do close at six. I believe they stop letting people enter the gates at 5:30 p.m.
As long as you're in the park and get into a line before 6, you will get to ride. Some stores also stay open so you can still buy food (funnel cakes!) and souvenirs but for rides, make sure you get through the entrance before the cut off time.
They close so people stop getting in to the park but also the lines for the rides close. They just keep riding the ones that were already in line before closing time.
The former is correct
They really close at that time
I agree with all who answered your question. I lived about 2 hours from there, many years ago. It wasn't always like this.
