My 23rd cruise with a three day pre-cruise jaunt in Rome, more information is written separately on my blog at cruisinbob.com
Embarkation: Port of Civitavecchia is located about 3-4 miles from the train station. Took the train from Rome then walked about ½ mile on a paved path to the port entrance, you then board a shuttle to the ship/check-in. You drop off your luggage at the check-in entrance (NOT where you get on the shuttle e bus), have the ONE page pre cruise documents printed and you are good to go.
Cabins: I had an Inside promenade view cabin on deck #6, actually the curtains were not often drawn as it affected privacy. Overall I was happy: a small fridge; a separate his/her's closet and an easy to use room safe and TV. TV had limited programming - you are able to view your on board account, make excursion reservations and view the daily dinning menu. I have one complaint: too many ship announcements at odd times.
Nice cabin, but did not draw the curtains often on the promenade.
