Re: points perks day
If you have a platinum pass, then you get to stay after the park closes and after all GP riders leave. You would get to ride for an hour after that.
If you don't have a platinum pass, then you don't get to stay for that extra hour. That's all. You're not affected at all. Mkay? 
Life is a highway and a roller coaster. Ride on!!
