Disney will manage attendance through a new theme park reservation system that will require all guests to obtain a reservation for park entry in advance:
“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 (Disney Vacation Club members can still make new reservations). Existing ticket holders and Annual Passholders will be able to make reservation requests in phases before new tickets are sold; we’ll be reaching out to these guests soon to provide additional details. We will resume new ticket sales and hotel reservations after that period of time. Theme park reservations will be limited due to attendance limitations and will be subject to availability.”
More details about this new reservation system will be released soon.
