Princess appeals to an older demographic than lines such as Carnival and Norwegian.

As noted above, these aren't people necessarily craving go-kart tracks and ropes courses at sea.

Our Pick: Celebrity - While both lines do well in this category, Celebrity's options are a bit more creative.

Both lines offer lovely suites.
