A platinum pass is a platinum pass, it doesn’t matter where you got it. You get all of the perks everywhere. This includes early entry.
Thanks CB. Unfortunately we won't be down on a weekend, so will miss early entry times. However I am going to assume that being there on a weekday when the schools are still in, will make it not as busy (and I always budget for Fastlane anyway), so the extra hour won't be needed quite as much. We hope to use it at CW for when "Yukon Striker" has early entry!
I am very pleased with the Platinum pass though, the savings add up when you use it as intended. With Cedar Point, Kings Island and Kings Dominion all within easy enough reach of us here in Toronto....there is plenty of scope to use it!
