Muppet-Vision is a much harder show to rebuild than something like FoLK was. FoLK was already a temp show with old puppets, costumes, and parade floats in a rushed structure. MV3D is a huge multi-media show with a pre-show, a number of animatronics, balconies, live costume performers, fog, bubbles, wind, water effects, facade walls and their lighting systems, and a 360 performance space. It is a substantial rebuild/move, and I understand why they wouldn't want to go through with it for a 33 year old show with mild viewership.
