Sailing on a small ship (784 people) is good and bad and noted by many people before me. Rarely do you have a crowd anywhere. We almost never shared an elevator with others. The ride was very smooth and that surprised me a lot.
The down side is that there is not too much to do. No movies; some entertainment which was ok; no place to avoid the children--and there were a bunch.
The Princess is old and in serious need of a rehab. The rooms are ok and have very good storage even though they are a bit on the small side. There are not nearly enough 115v plugs. There were too many international outlets so I strongly suggest bringing some universal adaptors for all your electronic gear.
