Depends on the view you are paying for. Standard faces the parking area. Preferred is basically water of some kind and Boardwalk view is, naturally, of the Boardwalk itself. So, you can get a view facing the canal to MGM, facing the parking lot/entrance to BW, of the Luna Park pool, of the quiet pool, the Village Green, or toward BC/YC that would be a Boardwalk view.
There are very few bad views at BW.
