Great to hear about, what is hopefully, a somewhat extensive upcoming refurb.
On my wish list, I always thought it'd be great if the unload section could be better utilized for a quick closing sequence. Right now the attraction closes with nothing but faded curtains and the logo; it such a dull, abrupt ending. Perhaps a small show scene could be built with a sci-fi/"home of the future" looking vibe and a 30-45 second voiceover about progress and technology and better things yet to come. Maybe add in some projection mapping to depict different looking prototypes of future items (fridge, TV, furnishings, etc.)? Then the final theme plays as the curtain closes and the CoP logo is displayed as everyone exits.
Such an addition would bring the show to a formal and cohesive close, bridge that gap from the fourth show scene to the "future," and leave guests with glimpses of that great big beautiful tomorrow thats waiting to be dreamed.
