The refurb workers most likely do NOT work for Disney. Those companies also have issues to work through before continuing their work, as do the suppliers of the hard and soft goods required to do the job. The Disney employees who work with them & manage the project may be on furlough. When those issues get worked through, I'm sure the refurb will begin again.
As pp said, $$ to pay for the work is most likely not the problem. Nothing about this situation is simple.
