Here's what I just got from a quick chat-
"in addition, at this time, we are temporarily pausing new ticket sales and Disney Resort hotel reservations so we can focus on guests with existing tickets and reservations.
Because theme park capacity will be significantly limited as we welcome guests back to the magic, we will manage attendance through a new theme park reservation system that will require all guests to obtain a reservation for park entry in advance.
We will post this information on our website and the Disney Parks Blog on how to obtain the reservations as we get closer to the opening of our Theme Parks and resorts."
