`morning all
Firstly, remember what was built for Germanys Rhine River was just the load area structure. Another much larger building would have gone behind this (search for my composites if you missed them)
Dear oh dear... firstly, the upper level to Electric Umbrella was actually ADDED in 1994 and is still in use today. The only upper guest level in CCore was in Centorium, and this was easy to get to and very visible both in position and means of access. When you bear in mind Centorium was split level and that you had to descend steps to get to the main shop floor that excuse just dosn`t wash.
Regarding Imageworks, it was closed due to evacuation concerns for assisted guests and to save money; a whole floor backstage dosn`t need insurance, tax, cleaning and the like. Plus there was a massive store space downstairs now when they ripped out the ride that had a gap between the shorter ride track and the store that needed filling. Remember JII 1983 had a very small store area. It obviously wasn`t making enough money.
The original pavilion guest flow was brilliant. You couldn`t miss the upstairs, nor the signs (both in ride and in the foyer) nor the means of access. The 1998 gutting of the pavilion ruined all that. The upper level wouldn`t have worked nearly as well with the shorter ride ending 500 miles away.
