We enjoyed our week on the Splendour of the Seas. I think I have been spoiled by the size and impressive facilities of the Voyager-class ships, but the Vision-class ship is very nice. Our stateroom, 2nd deck forward, had a porthole but was still light and comfortable. In the future, though, I would be reluctant to have a room that has an interior adjoining door, as it means you have a chair instead of a divan, and our neighbor opened the door one or two times - though we had asked that it be locked.
Another caveat: RCCL puts a six-pack of soda and two bottles of water on the room desk and charge ($8.60) for it if used. We didn't want it and stowed it in the closet. Of course, when they saw it was 'gone' we were charged for it on the final day and there was no time to do dispute the charge.
We stayed at the Marriott Courtyard at the Venice airport the first night, and a week in advance I was able to arrange a trip to the port for 33 Euros through the hotel.
