We just got off the Spirit on 7/19, third cruise for us (have also sailed on the Pearl and the Escape), hubby, me and our 14 year old daughter. We flew all the way from Oregon to London a little over a week before the cruise. Spent some time touring London, Paris, Naples and Rome and finally took the train from Rome to Civitavecchia the morning of embarkation.
The train was very easy, but many people were stressed out and on edge. The train we were on went from Rome to Ostiense to Civitavecchia, and onward to Milan. The sign just said Milan. You have to watch the train number and time, and ask if you are confused. Much easier then stressing out that you are on the wrong train. On disembarkation we walked back to the station, walked in and bought our tickets back to Rome and were on the train in 5 more minutes... for 5 euros each. Super easy and no reservations needed (we had reservations pre-cruise.)
The room:
Quiet cabin, forward of the forward elevators. Not much hallway traffic. Did not hear neighbors thru adjoining door. When sofa is made into the bed, the main room is essentially one giant bed, no room to get to balcony without walking on sofa bed. This was expected and did not bother us. Plenty of hot water for showers. Cabin was clean and comfortable.
