Just to clarify for others reading .... because the "blogger/website" that first announced that non-Disney hotels would be offered 60 day FP+ ............. They said that the Good Neighbor Hotels would be included in this, which is not true ....... causing some confusion.
The Disney Springs hotels are NOT "Good Neighbor Hotels" ...
so Doubletree is not a Good Neighbor Hotel.
Disney Springs hotels are "Official Walt Disney World Hotels" ......
as compared to the Disney hotels which are called "Disney Resort Hotels".
There are actual specific Good Neighbor Hotels, they are on the following list
and to date they will NOT receive Disney perks as was claimed by said website.

And considering there are over 50, if they are included later it could very well impact FP+.
