Parks in October?

I have yet to go to GADV this year and I want to see if I can go some time next month on a Sunday. I'm wondering: Will all of the rides be open and operating and would it be a good idea to go in October at all?

I can't speak for GADV becuase I've only been once a few years ago and that was in August. However, I've been to Kings Island (Multiple Times) and Cedar Point in October and I think it's a wonderful time to go! The temperature is cool, the park, suprisingly, isn't packed at all. If you go on a sunday it's pretty much like going on a weekday. There are virtually no lines. Also, try to go on a day when it is relatively cool, like 50-60 degrees. Not very many people want to visit a theme park in that type of weather. I love going to parks in October. Really nice!
