I don’t think booking categories are stipulated in the contracts. They’re under
DVC management’s control. When BWV opened there were two booking categories - Standard (same as now) and Preferred (BW & P/G). A Boardwalk view was only a request, just as connecting rooms at Poly is a request. After several years (and probably numerous ugly scenes at the front desk when people found out their request had not been granted) the Preferred category was split into two categories, so a BW view could be booked. It’s the same with Poly - the Standard view category would be split into “single room” and “two connecting rooms” categories.
