I *never* get season passes to parks, but this year I got a Six Flags pass. I had already planned on going to SFWoA and SFGAm once each, total cost, $75. Even if I got a $10 discount on each, that's $55...a penny more than a season pass costs at SFWoA through June 14!
I would urge anyone getting Six Flags passes this year to make your first trip to SFWoA. You can get them at Giant Eagle grocery stores, and they even come with a one-time parking pass. The same pass costs $85 at SFGAm! GREAT deal!
