Lines will be very short and you'll have an amazing time. Bizarro, Safari (kind of) and Mine Train will probably be closed for the season though. Skyway will probably be temporarily closed until Holiday in the Park.
Also, it's Grape Adventure that weekend if you're into that and (if you care) Safari is open for people who pay the Grape Adventure upcharge with the safari option.
Bummer about Bizarro. Are all the other major coasters expected to be running? I was thinking of taking at trip there next weekend. Thanks!
