A few other things to note:
1) None of the BCV balconies face toward the BoardWalk area and Crescent Lake. Only Beach Club hotel rooms are located in that portion of the resort.
2) About 1/3 of the BCV balconies are very close to Epcot Resorts Blvd--the main road which services Boardwalk, BC/YC, Dolphin and Swan. Cars, theme park buses and all manner of motor vehicles travel these roads.
2a) The rest of the BCV balconies have either a woods view or they overlook one of the pools.
3) There are villas on the ground floor which have concrete slab patios rather than elevated balconies.
4) Bear in mind that balconies aren't always the calm, peaceful, private setting some guests envision. If you look at the first photo "Simba's Mom" posted, you'll see how close together the balconies can be. You could have a neighbor sitting on a neighboring balcony 10' away from you (or directly above / below you.) Or someone talking on their cell phone. Or a group of people chatting / laughing / drinking / otherwise enjoying their evening. Or kids playing with toys. If your balcony overlooks the pool, you will get noise from folks swimming below.
Just want to make sure you don't have romantic visions of yourself and spouse sharing a glass of wine with only the sound of crickets chirping in the distance. More often than not, there are other nearby guests with their own ideas of how to use the balcony.
That said, we stayed in One Bedroom villas from the time our kids were 18 months old. When they were small enough for the porta-crib, we put them to sleep in the master bedroom and relaxed in the living room. As they got older, we'd put them to sleep on the living room sofa bed and go on with our lives in the living room. That's the benefit of staying in a One Bedroom suite / villa.
