So the BCVs are not known for their views. There are no lake view rooms and those that used to have views of Epcot are now mainly blocked by trees. The rooms manly overlook a lagoon, woods or gardens.
Also, I would not request room numbers. I would instead request what interests you in words. For example, high floor close to elevators, or parking lot or whatever. If you just give the room assignors numbers, they won't have anything to work with if your particular rooms aren't available as they wont know why that particular room appealed to you.
