I agree with Deb - there are more BWV preferrred. They are about 60% of the resort. BWV has 97 dedicated studios + 149 lockoffs so a possible 246. So 60% would be about 148. Boardwalk views are about 20%, so about 49. BCV has 36 dedicated studios and 74 lockoffs, so a max of 110.
Another factor is the BWV preferred are usually the last rooms to book at BWV, more standard and boardwalk views are booked at 11 months.
