Lately, I had been alone, waiting, thinking about WDW (as I do oh so often,) and I had started to think about something that I had not taken into consideration, yet. How much did it cost to build those things? I was wondering what I estimated the most expensive and the cheapest rides of all time to be. I figured that the most expensive ride would probably be World of Motion, but made just a wild guess that the cheapest ride ever was Dreamflight. I'm not talking about shows and such, just rides. I figured that Dreamflight probably would have cost $30 million to build at most. Does anybody have a more accurate guesstimate, and/or could tell me the most expensive and/or least expensive ride? I've been wondering what they were.
