We have sailed RCCL and also Princess. We just had a 10 day on the Sun Princess. We enjoy both lines. We prefer the smaller ships (Grandeur) although we were on the Adventurer and didn't like the size of it. On Princess we sailed the Golden and the Sun. We found the crew on both lines were very accomodating and friendly. I don't think you would be disappointed in trying Princess. I can only speak for myself I know I like both lines. I like switching from line to line even though I know you don't earn the status that others do. (Elite, Platinum etc.) We choose the line according to the itinerary. Have fun deciding.
