Ok why didn’t they do it like fast passes and just let people within a 60 day window reserve??
According to Disney: "By June 28, all Guests will be able to purchase new Disney Resort hotel packages and theme park tickets and make their park reservations for arrivals starting in 2021 as our phased reopening continues.
Guests will be able to view park availability online prior to purchasing their tickets. Please note that park reservations are limited in number and subject to availability. Availability can change until the reservation is finalized." (My emphasis added.)
The way I read this, if someone wants to go to a Disney park in 2021, when Disney starts making tickets available for sale to the general public, the purchaser will either: (1) have the option to make park reservations at the time of purchasing their ticket(s), or (2) be expected to make park reservations at the time of purchasing their ticket(s). If either of these are true for new ticket purchases, if Disney restricted the park reservation window to 60 days for people with existing 2021 resort reservations and tickets, then it would put such people at a distinct disadvantage in obtaining park reservations relative to people who can purchase new tickets for 2021 beginning on June 28th.
In other words, if someone with an existing January 2021 resort reservation and tickets had to wait until this November to make their park reservations because of a rolling 60 day window period, they will have lost their priority over anyone buying individual park tickets on June 28th (assuming the person buying new tickets has the ability to reserve a park when they buy their new ticket).
That being said, people with existing 2020 resort reservations and tickets are in a different boat. It would be nice to see them have some measure of priority in making park reservations, at least initially. I haven't seen anything saying if/when park tickets for the rest of 2020 will go on sale. Hopefully, those with resort only reservations in 2020 will have some priority in purchasing park tickets if/when they become available.
