As somebody who travels with my sister or a friend, I can comment on the space available when the bed configuration is for 2)singles.
We find that the Veranda staterooms are much better suited to our needs.
The rooms have about 3 extra feet of length within the room (above the French Balcony rooms).
The veranda balcony affords us some additional privacy.
And most of all - there are 2 banks of drawers for our clothes. (The French Balcony rooms only have one stack of drawers)
