Just repeating and clarifying -
There are three booking categories at the BWV:
1. Standard view
2. Preferred View - Pool/Garden
3. Preferred View - Boardwalk View
As already posted by others, the two PV categories cost the same amount of points. The standard view category costs less points than the Preferred category. You know when you book which category you have.
The Boardwalk view rooms make up slightly less than 20% of the available rooms and book up well before the Pool/Garden rooms. As Crisi posted, they are not usually available at 7 months, but sometime you can get lucky. May is one of the easier months to "get lucky".
