We went a few years ago in september for our first wedding anniversary. We had such a blast and I actually rode all the roller coasters in one day. YES FOLKS, one day (but at the end we had blisters on our feet...lol).
What was so great about going at that time, about a month or two before going, I looked online for different deals to cedar point. What I found was a nice room right there at Cedar Point Resort for something like $98 a night. Included in the room price were 2 tickets into Cedar Point and being able to enter the park a half hour before general admission. It was great to ride the new ride (millenium force at that time) about 5 times in a half hour time period. So, if we were to have paid for the tickets ourselves, we would only have paid about 50-60 bucks a night for the room right at cedar point. No parking fees, I could go out and return to the park at any time. No standing in lines to enter the park. It was a totally awesome experience.
I hear that at Haloween they really deck things out spooky and would love to take our kids there some day during the haloween season.
