75% of BWV is preferred view; different sizes of rooms are intermixed throughout the resort. Best preferred view is "boardwalk" view (only about 15% of all rooms in the resort) which you can now reserve as "boardwalk" view and you are locked into it at time of ressie if it is available. That view overlooks the boardwalk and the lake looking toward YC/BC and Epcot (you can see high fireworks of Illuminations). The other preferred views overlook the Luna (main) pool area, the quiet pool and the lagoon heading toward MGM. All of those face away from Epcot and, depending on location, you may see part of the lake, YC, Swan/Dolphin, or top of MGM. Other than boardwalk view, no specification at time of ressie is assured. Requesting specific room numbers is almost certainly a request that will not be honored at time of check-in; i.e., if the rooms happen to be open when you arrive, you will get them, but they will not do anything to hold those rooms open for your arrival.
