There is a Boardwalk View at Boardwalk Villas, not at Beach Club Villas.
Boardwalk Views face the Boardwalk and the Beachclub. They are about 20% of the resort and are probably second in popularity to the 20% of the rooms that are standard view. 60% of the rooms are preferred view - if you book later, you will probably only have the choice of preferred view.
With Boardwalk View, high floors enable a better view of the fireworks, but less people watching. Farther down the hall gives you better view of the fireworks, but less people watching and a long walk down the hallway.
