We picked the Fascination because we had some business to do around the Jacksonville/North Florida area. Carnival is the only cruise line that sails out of Jacksonville port.
We arrived two days earlier to take care of our other business. Looking back, we were glad we arrived into the area early so there was no pressure to go straight from the airport to the port.
We took a taxi to the port for embarkation. It was $33, we stayed in the Hyatt Place hotel- very clean, nice large rooms with free hot breakfast. Hyatt Place also includes a free shuttle that goes between the hotel and airport, or any destination within 3 miles. There is a big shopping center within 1 mile of the hotel.
R196 on Rivera Deck is an ocean view with a rectangular window (not a small round port window). It is on the most bottom level deck for passengers toward the back of the ship. You can feel/hear the engine rumbling but it did not keep us awake. There is a third fold down bed mounted on the wall. Since we were just two traveling, they folded it up and kept the ladder for the third bed in our closet.
This room also has a door to connect with the room next to it.
R196 is very close to the stairs/elevators at the back of the ship, so it was very easy to get to our dining room, and the lido deck buffet.
It is across from a crew only door/access way, we did occasional hear that door open and close, but the sound did not bother us.
