Last year I bought a home and left the shell and reworked everything else. It costed a ton (or 2) and was a ton of work. Deciding where the light switches go, what way the doors turn open, adding a bathroom etc. I can't imagine how much work this thing is. Water management, lighting of the ride at night, music, speakers, sound effects, show scene's, a complex coaster system, theming, airco, colors, signing, story development, plants, roofing, security, safety, maintenance, cleaning, landscaping, queue management, personal etc.
