Is there much difference between a Superior Ocean View Stateroom with Balcony and a Deluxe Ocean View Stateroom with Balcony on the Navigator of the Seas? I have booked a Superior D3-6548. I am a little confused as to how the D numbering system works. My main concern is that the room is by the elevator, the RC employee I spoke with assured me it would not be an issue. What does everyone think? Can I find a better room than this one? Is it worth the extra $ for the superior over the Deluxe? Some descriptions say that the superior has a couch on the balcony while others do not.
