there is no sixflag but there is a sixflags
Well, It depends. Where are you and which Six Flags do you want to go to?
Six Flags is a very fun place to take the family. Six Flags. more flags. more fun Six Flags
I'd assume the price varies depending on which park you're going to. In my region, Six Flags Great America is closest. Average admission price there is between $60 and $70. Unless you have a discount, the trip isn't worth it (in my opinion). When you have a Coca Cola can with the specific "coupon" on it, you save around $20 on your admission. Then you have the season pass option. If you plan on going more than two or three times, it's totally worth it. It's about the same price as the full price admission ticket. When they're "on sale", they're the same price.
