If the publication of the book is intended for sale or distribution, then that would likely require permission from Disney for any photos which are identified as being taken on property or those which involve iconic Disney landmarks, structures, etc. ; I don't honestly know the full legality - whether or not this could be fought legally with Disney on some grounds (wdwfigment???) but I'd certainly expect Disney to pursue it as they tend to be pretty aggressive with protecting their property.
Personally, I have avoided publishing or selling photos of Disney property, which I've defined as those things that are clearly identifiable as Disney property or could only be found on Disney property. ; If I ever did, I'd first make an attempt to do so legally and with permission, which supposedly can be hard but is possible (I'm sure Tim has some knowledge on that issue). ; But I don't think I'd be willing to distribute or sell any of my photos of Disney property unless I had permission.
