In our own family we have different favorites.
Our son-in-law (25 years old) LOVES BWV or BCV because it's close to ESPN (he's quite a sports fan). He also likes the easy access to Epcot and MGM. The BCV pool is a favorite also (a mini water park). My oldest daughter also votes for the Epcot resorts as her favorite. She likes the whole area.
Our youngest daughter (20 years old) prefers VWL, although the Epcot resorts are a close 2nd.
My husband and I prefer VWL (quiet and soothing for tired people who need a rest). Magic Kingdom is also our favorite park and VWL is just a boat ride away from the Magic Kingdom.
We went to Olivia's Restaurant in January at OKW and took our kids and they said they would like to stay at OKW sometime. The sun was shining and OKW looks beautiful with all that lush landscaping, palm trees, and great Florida feeling. It also has basketball courts and a new themed slide at the pool. Very lovely.
If I were you, I'd make a point to visit them all and find out which one you like best. And if you are like us, each person in your family may have a personal favorite.
