Do cedar fair season pass holders get into the park an hour before opening at Carowinds?

NO

I don't think so but I would call just to make sure

Yes.. Spoke to a Mngr. On Sat. Night. She said an Hr. Earlier for Fury 325 & Copperhead Strike only...

Yes but it's 30 mins not an hour at Carowinds

Not that I'm aware of. I came from Tampa Florida and went there by the time I got there they were already open. But for a heads up make sure you get the fast lane pass so you can get in front of the line cuz you will need it trust me
