CTX was part of the originally opened Dinoland USA, Dinorama was built later on and I believe it became an either / or proposition between Dinorama or the Excavator. I suspect had they built the Excavator that Everest wouldn't have been built.CTX was and is independent of Dinoland USA. The latter just had a backstory written to better pair it with its neighbour. Dinoland was explained to me as being able to be removed in around two weeks. It was built with minimal buried utilities for example (power and I think data) to make it a quick and cheap removal. Virtually everything is just bolted to concrete as opposed to being a building with foundation.
