ride closings during halloweekends

I have never been to the halloweekends at cedar point before, and my fiance and I are going for the first time at the end of september. I read that some rides are closed on friday nights. For any of you who have been there on a friday night before, are there a ton of rides closed? My fiance said he only really wants to go on millenium force and maverick- I'm hoping they're open. Thanks all!

Millenium and maverick will be open friday night during halloweekends.

Most of the "big ticket" rides are open on Friday nights, along with a handful of family rides (like Iron Dragon and Wildcat) and Planet Snoopy.
