As to the OP, we stayed at WBC in August 08 - we had a 2BR unit and it was unbelievably great! My DH is asking to go back there! He never asks to go back to FL! (He just has to, because I do the vacation planning, and when it comes down to it, he loves it!)
The resort is beautiful, the units are spacious, clean, luxurious. We had planned a resort day - and for that day, we did enjoy the pools and the kiddie playgrounds. At the time I had 2 girls - 5 and 10. We played a round of mini golf, we played on the kiddie playgrounds, we swam in both pools, we hung out in the unit - it was a great time!
Brian mentions that the on-site dining leaves somthing to be desired, and that is true. On our resort day, we carried out at the closest Giordanos. Other days, we ate at the parks, or offsite before coming "home."
One thing that stood out to me - I found that there was plenty of parking available - we are rental car people (or drive your own car people, depending upon airfare - we're not that far away). We have stayed on WDW property before, and we found that even when we couldn't get a "good" spot near our WBC unit, it was still closer than when we couldn't get a "good" spot at Pop or at SOG..
