What size unit are you planning on for your stay?? If you want a 1 BR, I would suggest OKW, just because they are so much larger than the other resorts, if you are planning on a studio stay I would suggest BCV if you are planning on spending a lot of time at the resort, since your DD would probably love SAB...if you will be going during the winter or do not plan on spending a lot of time at the resort, then just pick the location you prefer.
Personally I do not care for the studios at OKW because there are no couches or easy chairs...it is just like a big hotel room. The other resorts have a sitting area with the sofa bed and an easy chair as well as the little table and straight chair. All of them are great resorts, so just pick the location that looks best for the trip you are planning if you are going to be in a studio.
