Thanks Dave and Dwayne. I know it is a little confusing - Carnival uses different naming conventions for various classes of ships in the fleet.I know you are trying to say it is the deck below Riviera where the Medical Center is on, and the same deck used for ports of call and tender boats.
I have a room with 2 upper berths on Empress Deck just by the aft elevators. I will keep it. I will have 2 children in strollers, so being able to "roll on, roll off" with no elevators during embarkation and debarkation would have been nice, but not a big deal.
