Maybe I misread the question, but 'boardwalk view' means that your studio will be facing the lake and boardwalk...lucky you!!!!!
Other views at the BWV resort are Preferred View, which is the same number of points per night, but facing one of the 3 courtyards which contain the quiet pool, the Clown pool, and what I call the croquet lawn(faces Swan and Dolphin and I think this is the area they were thinking of putting a croquet court in). I've also read that the courtyard that faces the boardwalk is also a preferred view . Standard view are those rooms that face the drive up entrance and are either above the valet stand or all down the wing that borders the entry (and ends by the parking lot/tennis courts)
So: your boardwalk view will look across the lake to YC/BC and you should be able to see Spaceship Earth in the background and high Epcot fireworks, and maybe even Wishes fireworks. I repeat: lucky you!
