Tip #1) Rides don't quite close at 10.
Or closing time, that is. A common thing I hear at Cedar Point a half hour before closing is "No, the line's over an hour long, and the park closes soon, so there's no point in waiting and being kicked out of line. We had better just head back to the hotel room." Well, if you have the time, and won't fall asleep, this isn't true. If you get in line for a ride and the park closes, they can not kick you out of line. The ride will keep running, all night if they have to! Just get in line before closing, and your day will be greatly extended!
