When BWV first opened, it was all one. Then people complained about getting the front driveway area so they split it up into standard for lower points and preferred for everything else.
Then about 8 years ago, they split the preferred into garden/pool and boardwalk, same points but actual reserved view. It was at the same time as they introduced a "room ready" room assignment system where rooms were not preassigned, you would be assigned a room that was ready when you arrived at the front desk. I think they thought that would cause problems at the front desk because there are few boardwalk view rooms compared to pool/garden. I spoke to member satisfaction at the time because when I bought, I was told room requests are filled based on date of reservation. Since I would have the home resort advantage at 11 months, I would have a good chance. This "room ready" system would throw that out. I guess they got more complaints because shortly after they announced the reserved views.
