Shan,
From that map, you'll notice:
The PV non-BW views closest to the elevator are Luna Park.
The quiet pool will put your further from the elevators (but will be quieter - especially during the day/evening when the pool can get loud).
There are no rooms close to the bus stop that are not dependant on the elevator. Actually, there aren't any rooms "close" to the bus stop. The bus stop is U on the map. Although first floor standard view rooms can cut across the lawn. The rest of us need to walk around or through the building.
The lobby is "H" - we did most of our coming and going through the lobby and down the steps onto the Boardwalk - but we didn't have a stroller to worry about. There is a breezeway between Luna Park and the courtyard by the steps. So if you take the elevator to Luna Park you can cross over.
The "back" of the hotel (over luna park and the quiet pool) will have a view of the Swan/Dolphin. From our room (BW View) which was right above "L" on the map we could see Illuminations fireworks right above the A - that should give you a good idea of what direction you are pointing. I'm not sure what direction you'd need to be to see any Fantasmic fireworks, although we noticed them from the boat one night.
