When 3,100-passenger Azura launched in 2010, it ushered in an updated vision for the very traditional P&O Cruises. Instead of targeting a mature adults-only crowd, this unstuffy British ship fills up with boisterous families, and caters to them with a more relaxed dress code. You'll still find some hallmarks of traditional cruising; the ship has black tie evenings, for example, and optional assigned seating at dinner. And another thing certainly remains the same: the experience onboard is quintessentially British, meaning you can dine on scones and tea each afternoon or order a pint at the pubs as if you're across the pond.
