Great question. I don’t think it’s a smoking gun that the parks won’t be open by then. The only thing we know for sure is VAH is cancelled. It could be for cost cutting, could be they don’t want to leave the park open until 1am during all of this, could be they don’t plan to have very many characters in the parks (at least not meet and greets) so it’s kinda hard to do an event like this, or it could mean the park won’t be open yet. Lots of possibilities. On one hand they haven’t cancelled room reservations yet for June and July. On the other hand TripAdvisor still has the note on all of the Disney hotels: Update from hotel: This property is temporarily closed until 07/30/2020.
The email said VAH is "cancelled due to the closure." That's pretty indicative. Otherwise they'd say something a little less vague, I'd imagine.
I can book Port Orleans: French Quarter on Hotels . c o m for stays beginning June 1st.
They have been incrementally pushing the dates back, with June 1st being the latest. One of the primary reasons is they want to gauge demand levels which is easiest to do by bookings. June 1st is likely out though.
