Technically, that's a copyright violation. Disney just opts not to enforce their rights for that sort of use.
Similarly, you technically can't take and post pictures of statues, paintings, some buildings, etc., and some rightsholders do enforce their copyright when people do those things.
Outside of things within the scope of fair use would be within Disney’s rights to restrict, but given the actual public policies and guidance on photography at Disney parks, I think there is a very strong case that noncommercial photography (for people are present as paid guests) is permitted by implied license.

Well, not buildings if they are in or visible from a public place in the US, at least under copyright law. (Photography of some, particularly government, buildings may run afoul of other law.) This may be different in other countries.
