We are booked the first week in August and we got an email. Here is what part of it said
An Important Walt Disney World Update
As we plan for the reopening of our Disney Resort Hotels and Theme Parks, we are keeping the wellbeing of our Guests and Cast in mind. And we’re here to help you as we introduce new procedures focused on delivering an enjoyable and magical experience for everyone who visits.
To manage attendance and foster physical distancing during this unprecedented time, we will be changing and suspending some Park experiences. In addition, we will also be introducing a new Theme Park reservation system.
Also, please note that upon reopening, Extra Magic Hours will be temporarily suspended.
Unfortunately, these new measures have required us to cancel any dining reservations, experience reservations and FastPass+ selections you may have made. We recognize the inconvenience this poses and we’re deeply sorry.
However, because you have valid Theme Park admission, you will have access to the Theme Park reservation system before new tickets are sold to other guests.
