I have visited, but not stayed in the WL. It is beautiful!
But by far the Epcot Resorts are our favorites. I would choose the YC/BC.
It is the BEST LOCATION on WDW property. You can walk to both Epcot (the International Gateway) and the Studios. You also have the choice of a pleasant boat ride if you choose not to walk. We have done both to the Studios.
We love Epcot. We have hoppers and actually end most evenings at a WS restaurant. We love them. Walking home after Illuminations is priceless.
You also have all of the restaurant choices of the nearby Boardwalk as well as the Swan and Dolphin.
SAB is the best pool on property. We love the occasional afternoon break, relaxing with an adult beverage (we are an adult only party), and swimming in the sand bottom pool.

Have a Great Trip
