BWVbound is right, none of us can tell you which resort would work best for your family. But I can see how hearing how other people made their home resort decision.
For us (two 30-year-olds, no kids yet), we knew we wanted to own at a resort that had walking access to at least one park (so that narrowed our choices to BLT, BWV and BCV). We also love the Food and Wine Festival at Epcot and we decided having 11-month access to make reservations for those trips was very important to us, so it was a choice between BWV and BCV. Then it came down to decor and the feel of the resort.
We just liked the decor and vibe at BWV more than the shabby-chic vibe at BCV. We like the activity of the Boardwalk both during the day and at night, as well.
We may add on on at BLT in the next couple of years (especially once kids come into the picture, we love CR and the private walkway to MK!).
