There's one other perk to the rooms way down at the DHS end, if you don't utilize the lobby often. Aside from being closer to DHS for the walkway, those end rooms are pretty convenient for the bus stop, as there's a door down at the end with a short walk across the street to the busses.
Personally, because view isn't important to me when I'm in the standard view rooms, I request 2nd floor...close to the lobby is choice #1, and 2nd choice is all the way down at the end so I'm close to the bus stop. 2nd floor for me is better than 1st, as the elevation provides a little more privacy, but remains easy coming back from the bus only dealing with 1 flight of stairs back to the room. On higher floors, you either have to be OK walking up 2-3 flights, or have to take the elevators, then walk that long long hall.
Note also that 2nd floor IS the lobby level at Boardwalk - you enter on floor 2.
In fact, my favorite 1-bedroom standard view is down that end - I think the room number is 2123 - it sits right on the curve of the building over the entrance door - has a strange layout because it stretches around the corner, and a huge balcony that wraps around two sides. And for a standard, the view is very garden/water like and peaceful:
