Now that I'm at a keyboard I can make a better post.
Observed the situation on the way out of the park at closing. The water was coming up through cracks and seams in the pavement starting up near the new Coke stand, down to about the photo booth pickup. There were employees pushing water out of the Emporium, so it might have been coming up through the floor in there as well. The water was running down the main pathway to a drain at the base of the fountain, where it was about half an inch deep when it went into the drain. There was fine silt coming up with the water, so it's a good bet that the flow was eroding the ground away under the pathway.
I would expect that the whole area of the main pathway in England will need to be dug up to fix the broken pipe and repair underlying erosion. I just hope that the Emporium won't need extensive repair work as well. Because of the location of the problem, right at the choke point into England, pedestrian flow is going to be a mess. They might possibly rope off an aisleway to keep people right up against the face of the theater. But that would take people right by an active construction site. It wouldn't surprise me if they just closed the park altogether, to allow repairs to be made in time for a Friday opening.
I considered getting some pictures, but the employees in the area seemed pretty stressed, and I didn't want to ratchet up the tension level any higher.
