We last cruised with Princess in 2009 with subsequent cruises on Holland America and Celebrity. After a wonderful cruise on the Ruby we definitely will be back to Princess in the future. Of course, we have been on some cruises that are better than others, but never a bad cruise, however, this was one of our best.
We stayed a couple days in Rome and then used Rome Cabs for easy ride to Civitavecchia. We got to the ship around 12:30 and embarkation was the easiest we have ever had, as we must of been on the ship with 10 minutes!!
We had a balcony cabin on Baja deck on port side almost to aft of ship. The only time we had any vibration was when ship was docking, but we were already up, so no issues. Cabin was obviously a long way from mid ship, but we love to walk, so wasn't an issue. Cabin steward was excellent!
