If you want a chance to see the MK fireworks from your room, request a room on the 5th floor (the 6th floor rooms have enclosed balconies so you would have to be outside on the balcony for the greatest effect) in the 5000-5034 wing (the even numbered rooms face the MK; the odd numbered rooms face the courtyard pool.) This wing also has the elevator that opens right outside Roaring Fork, so it is convenient to get food/snacks/drink refills without having to walk too far. The laundry is also on the first floor near this elevator.
If being close to the pool and boat dock is a greater priority than being able to see fireworks, request a room on the first floor in the 1000-1014 range. Four of those rooms (we were in 1002) are on the end of the wing and actually face Bay Lake but are woods view because you look out into trees, with a view of the boardwalk to the boat in the distance. Those rooms have a private stone patio and we watched deer from there. Additionally, a door to the outside is right there, providing quick access to the pool or boat.
Lastly, we were surprised how much we enjoyed room 2110, which is right off the lobby (so we never had to use an elevator.) It was super convenient to the bus stop and gift store. Even-numbered rooms in the "1" wing (as opposed to "0" wing) are also categorized as woods view, though most of them face the WL Villas or the Villas pool, and are a LONG walk to get anywhere! Given my choice, I would always pick "0" wing over "1" wing.
And this is probably far more information than you were expecting, LOL.
