Last year when we stayed at YC Concierge, we had a lagoon view which was directly over SAB. It was a LONG, LONG walk to the lounge. Sorry don't remember the room number, but it was at the very end of the building closest to BC. So just keep in mind if you want a room closer to SAB, it will be further from the lounge. Also remember that a room closer to SAB will be noiser with sounds coming from the pool area.
The year before we stayed in room 5161 which was my absolute favorite. Perfect view of Boardwalk and Epcot. I could see the Eiffel Tower from my bed. It was also a very close walk to the lounge.
