I hear you, but I would have to substitute any coaster for IASW. I would die before going on RNRC (seeing as riding the ride would kill me anyway).
I think UO has more incentive (still paying TM) to open as soon as possible and less prep work (smaller resort) than Disney. If I was Disney, I would be willing to let someone else open first and take the risk that something goes wrong. All it takes is waiting out the 14 day incubation period, which in the scheme of things isn’t all that long to wait. I am one of the people who got the cancellation email today and honestly it was almost a relief. I will go to the beach in June and wait for August for Disney.
