We've sailed on a number of cruise lines, from Norwegian to Seabourn and Princess is the best in our book on the basis of quality and value. (Nothing can beat Seabourn, but the cost such that we can't make it a consistent way of life.)
All factors taken together -- quality of ship, food, entertainment, cost of extras and service -- Princess truly delivers and the 14 Transatlantic turned out to be our best voyage on Princess yet.
Embarkation: Smooth and easy (although we're Platinum, so it's typically easy). Tip for those who aren't Platinum -- Don't arrive too early or you will simply be placed in a very long line. If you arrive about 90-120 minutes after the "launch" of boarding, the lines should be much shorter.
Very nice location (highest grade mini suite). Right in the middle of the ship, which was helpful during a somewhat bumpy part of the crossing.
