Experiences and room assignment can vary so much, and influence opinions for sure.
Our home resort is BWV, and we are mostly there in 1 bedrooms, but usually pool/garden/standard view. Our very first BWV stay in 2012 was a 1 bedroom boardwalk view....on the first floor. I did not enjoy it at all, I felt people were walking right in front of our living room window all day, and we never went out just to sit. Only other BW view was our grand villa stay. That was SOOOO nice, but as other have said, noisy at night before the performers stopped, usually around 11 PM
Our only BCV stay was a 1 bedroom, located at the very end of the hall next to the parking lot, so not as short of a walk to Epcot/pool as we'd hoped. I enjoyed SAB very much, kids and DH thought it was just fine, but they've never wanted to stay again just for that. I enjoyed the stay there, and would go again.Room layouts were similar, so no preference there.
So, there is a chance you'll be on the first floor with a Boardwalk view, just something to keep in mind. I also LOVE sitting on the balcony with a glass of wine or a cup of coffee, and have enjoyed many BWV 1 bedroom stays for that, just with pool/garden or standard views, but I'm also not against trying a BW view again.
