Pity they can't or should I say, won't find the money to open the upstairs part again. Add a fast food restaurant up there if you must to make some money and surely it would pay for itself over time? To be honest, 'back in the day' I never found the upstairs quite as exciting as some are painting it. It was worth visiting certainly and had some charm, however it wasn't a stand out feature of Epcot or even the Imagination Pavilion in my opinion anyway.
However is does bug me slightly when we go knowing that space is vacant up there, they certainly could do something with it and should do. The view alone makes me feel 'cheated' that we're no longer allowed to visit it and I'm sure many others agree.
