I would love to know how much money is saved by rotating coasters from one park to another vs. designing and building ones from scratch.
Let's just say for argument's sake a new coaster cost $10M from start to finish. How much does it cost to dissemble an existing ride, pack it up, ship it across the country, build new foundations, reassemble the steel and build loading and queue areas? Is it only half of the $10M cost? For some reason I think it would be more than that, since you still have a lot of labor involved with dissembling and reassembling the coaster. And shipping of all those components cannot be cheap.
There has to be some savings, but I'm not sure it's all that much. I think it is more about SF being able to move the rides around once they wear out their welcome (or having technical problems), as opposed to cost savings.
