Not sure where you are seeing a difference mentioned. For
DVC, there is no "preferred" category of studios at VGC, just the studio. Sarasota Springs at WDW has preferred and standard, and the classification simply indicates location of the applicable building on the site. Boardwalk Villas also have standard and preferred rooms and the classification refers to location of the room, and "preferred" is really now two classifications -- boardwalk view and pool/garden view. I am also not finding a "preferred" classification in the rental section of Disney for the VGC villas.
