Some people request pool view which is pretty. Others request Epcot side. Many but not all rooms on that side enjoy a partial view of the upper effects of Illuminations. A road runs close to BCV at that point which bothers some people although not my family as we enjoy the trees or woodsy area on that side.
Some ask for close to the lobby or close to an elevator. We find no room too far from one of the elevators and have enjoyed views on every side. The only thing I personally don't care for is first floor. Others love it.
This probably isn't much help, is it? We've really enjoyed every location we've had other than the first floor....but that's us.
Have a great time at BCV.
