Not Disney but I have a trip booked (booked in October of 2019) to Europe to go to Europa Park & Efteling in September/October 2020. I just saw that Europa Park (similar to EPCOT & located in Germany) is opening May 29th. They are employing some of the same operational changes that Shanghai is employing. From the Europa Park website:
Dear guests and friends of Europa-Park and Rulantica,
from 29.05.2020, Europa-Park will be open again for you!
The
six themed hotels, the Camp Resort as well as Europa-Park Camping will also be welcoming you from 29.05.2020.
The
hotel restaurants will be re-opened step-by-step from 18.05.2020, beginning with the outside areas only. Only the water world Rulantica will remain closed until further notice.
We welcome the national easing of Coronavirus related restrictions announced by the Baden-Württemberg government on 6th May 2020 and have been intensively preparing for a re-opening of Europa-Park, our accommodation offering and the gastronomy, in close cooperation with the authorities.
Health and safety of our guests and employees have always been our highest priority. It is our goal that you continue to feel safe and comfortable when visiting us. We have therefore decided to start the season with a limited number of visitors from 29.05.2020. We will be offering
date-specifiy tickets for the 2020 summer season from 13.05.2020 via our online ticket shop. Our park area is large and spacious which means there is enough space for all visitors and employees to keep the mandatory minimum distance.
We kindly ask you, dear guests, to observe the manditory minimum distance as well as the additional hygiene requirements which apply until further notice at Europa-Park.
We look forward to also welcoming our international guests as soon as travel from and to our neighbouring countries is possible again.
So this could give more insight to what WDW will do and I would think Disney would watch how things go at Europa Park as it is one of the biggest theme parks in Europe.
Food for thought!
