First, Rockit has much, much more themeing than most all Six Flags rides. Second, GP members come for location and family friendlessness. Would a normal tourist group go to a park two hours away from a metropolitan center or to the theme park capital of the world? And would a GP member with a family with little kids go to Cedar Point, or Disney. They would go to Cedar Point if they didn't have kids, but Disney's family rides make it a better choice.
You really don't don't see my point what so ever.
