I went last year on the 24th I think and it was pretty dead. I got on the front seat of TTD and MF twice as well as getting to ride all the coasters in the park and some flats. The park is also open partially for the first week of September was and I would expect it would be just as dead than since most schools are in by then. I'm hoping to get up to the park on the 25th or possibly even taking a day off school next week and go up to the park. I definitely cannot miss my yearly Cedar Point this year, especially with maXair at the park now.
