My experience with booking rooms at Disney hotels has been one of frustration sometimes. Because of the sheer number of rooms they turn over, when you book a reservation they do not let you request floors, particular views, etc. (And if they do, the notes are seldom read in advance of you showing up to the front desk at check-in.) You can pay additional for a view room or a suite, but unless the suite you booked is only available on the top floors with the view you want, there is no guarantee you will have the view YOU want. And if you pay more for a "view" room, it may not have the "view" you consider to be a view.
Also, they do not normally upgrade rooms as they are normally sold out during peak seasons (or are trying to book those rooms at a premium). For example check-in is at 3pm (I think). But don't count on your room being available before 4pm (or later). Even if some of the rooms are available, the front desk normally gives out the standard answer of "please return after___ to get your room assignment." During the peak seasons there can be a lot of "hurry up and wait."
Enjoy your trip!!
