There are no bathrooms in the Epcot lounge fyi. And I don't think they'd put bathrooms in a new lounge anyway, as that just encourages people to park in there. As for plumbing, I think they'd need floor drains at a minimum for the freestyle machines wherever they went, and a reasonable water supply with filtration. Since the building shares space with an ice cream shop and a bathroom, I'd expect they could make this work easily in the Stitch space. My hope is that they don't do that, of course. Anywhere in MK would be overrun with people each day unless the went big and took over Pinocchio Village Haus.
