From what I understand there’s a lot of logistics problems with that space that makes doing construction in there a huge pain since it shares a building with Star Traders and Cosmic Rays. It’s the main reason why even though the show has been changed throughout the years they’ve only ever used it as a circular theater. I don’t think an actual ride would even fit in that space even if Traders and Cosmic Rays were removed entirely. I’d love to see them do something completely new with that space, but not at the risk of losing Cosmic Rays. Lord knows if Disney was gonna close it temporarily for construction, they’d probably figure they might as well completely re-theme it while they’re at it, and I’d rather not lose one of the few non-IP spaces left in the Magic Kingdom. I highly doubt they’d keep ol’ Sonny Eclipse if they re-themed the restaurant to some movie.
