If you buy a 2016 season pass (before Monday, I think), the cost for a gold pass is $51. This includes free parking as well as admission for fall 2015 and all of the 2016 season. Normal price for the gold pass is $164. You have to buy at least two passes to get the $51 price. If you don't live in St. Louis but close to another Six Flags park, they're running similar deals
