SeaWorld added the "get the rest of 2021 free" on passes
The big chains all now have the deal doing
If you have been following I grabbed the Cedar Fair Platinum deal when it came out. Part of my OffYear strategy. Quickly Six Flags added the same deal (HOME PARK ONLY - full show with details here) and finally it looks like SeaWorld added it after Halloween. Plus: Limited-Time Offer: Save 20% online so a better deal than I got it last year.
Yes, if it's not clear if you are getting a pass it's VERY worth it.
