Sounds pretty expert to me.
I'm going soon, too, with the same room category and here's what I pieced together from the helpful people in this thread, regarding
"deluxe" rooms in the main building (RPC) ...
KING (see floor plans below)
Six "turret" or "octagon" rooms, roughly 648 sq. ft. each. No balconies. Three these rooms with monorail views and three with listed "lagoon" views from which you can see fireworks. The room numbers of the king turret deluxe rooms that have at least some castle view has been listed here as: 4021, 4421, 4321.
The rest of the king "deluxe" designated rooms, which I've seen listed as either six or nine, king "deluxe" rooms are all on the "hidden" second floor, accessible by the bird cage elevator, and feature "theme park views." These used to be called the honeymoon suites and are basically the same size as the standard Grand rooms. All feature a jacuzzi tub, something not in a regular room, and a balcony, in addition to the view.
QUEEN (see floor plans below)
Six queen deluxe rooms, on the third and fourth floors, all roughly the same size (634 feet), though they come in two different configurations. All have either lagoon (can not see the parks) or pool views.
The more triangle shaped rooms have a large double balcony with a view of the beach and pool, and a large, separate "foyer" area that has a wet bar (sink, fridge), along with the closet, which separates the sleeping area from the bathroom. These are rooms 4322 and 4422*.
*Note we stayed in room 4422 and liked it. Lots of space and loved the large balcony. Plenty of room for a rollaway, if needed, either in the foyer area or along the wall next to the sliding balcony door.
The squarer-shaped Queen deluxes have the wet bar in the sleeping area, standard-sized balcony and an over-sized garden tub (non jacuzzi). They are much wider, but not as deep as the others, and can actually fit a rollaway bed NEXT to the two queen beds. Those room numbers are: 4319,4419,4320,4420.
-A recent poster noted that, post-renovation, RPC deluxe rooms now have fold-out sofa beds. In the past they just had non-covertible loveseats.
