Transatlantic cruise from Barcelona to New York City --The main reason for taking this cruise was the itinerary and the cost was relatively reasonable.
Embarkation/Disembarkation: In Barcelona we had an embarkation window of time assigned of 1:00 to 1:30, arrived, and flew through onto the ship. Fasted embarkation I have ever experienced on any cruise line. Once on the ship, we were hit with a wall of people! Many enjoying the first bar they saw in the atrium, most others standing in a mob waiting for elevators. We used the stairs. Carnival did a great job of getting people off ship in NYC, though mighty early because they had a christening party planned for that afternoon. Organization fell apart in the terminal but that was not Carnival’s area of responsibility. Once aboard our airport transfer bus I looked across the street at a line of passengers and their baggage that went down the street and around the corner! Very happy we had purchased Carnival transfers.
Elevators: A new system that generally worked very efficiently, unless there were many people at one time, on multiple floors, trying to access them. Use a keypad and enter your floor and you are assigned a car that is programed to go to your floor (among others). But, when that car arrives and is full, you have to start over. TV screens on some floors, that displayed car letters, and what floors they were going to, helped a lot.
