My experience is that there are a lot of upper 30's lower 40's, and the entertainment targets the 40-ish age bracket. On the Voyager-class ships, I have seen statements from RCCL that 1/3 of the passengers are children...but don't let that make you're decision for you. The children have their very own sections of the ship, and spend most of their time there. RCCL, especially the Voyager-class, does seem more family oriented than Princess, Celebrity, or other RCCL ships. If you would prefer to be on a similar ship sans the children, try the Radiance-class ships from RCCL.
