We stayed on the "hump" on Navigator and loved it. The balcony wasn't any bigger, but was more secluded as the rooms to your left and right don't stick our as far as yours does. Also, the location near the elevators and stairs is PERFECT! You don't have to walk for miles down a narrow, winding hallway to get to your cabin. We were worried about the noise from the elevators, but never heard a thing.
The hump rooms are my fav and we booked one for our next cruise on Liberty.
