Thankfully, after being a fan for years, I can decipher Disney-speak:
"While we’re currently accepting reservations starting in July 2020 at both resorts, as this situation evolves, timing may continue to shift."
= Just because we are starting resort reservations on July 1st, that does not mean July 1st is the date reservations will actually start. We may continue the rolling cancellations throughout July. Or, start reservations in June, but locking them to stay within capacity limits. In other words, it's a non-statement meant to take space in this page.
"As we continue to follow guidance from government and health care officials regarding how we’ll be able to reopen our parks and resorts in a responsible way, we may also need to make real-time adjustments to booked experiences, park tickets and park passes."
= We may continue to cancel packages, cancel your dates and extend your park tickets through the end of the year, and cancel your after-hour events, such as Villains, all at the last minute possible.
There ya'll go! Wish we had a date like the Universal fans....
