At the forefront of deluxe cruising on mid-sized ships carrying between 900 and 1,000 passengers in sublime comfort. These outstanding vessels strike all the right notes and – surprisingly – also boast some of the best entertainment at sea, from top-notch Elton John and Billy Joel tribute acts to the innovative iLuminate music and dance shows. Spacious and well appointed, nearly all cabins and suites have full baths (as opposed to showers). Serenity is a slightly more spacious version, but both feature excellent alternative dining, with a gourmet-quality Italian restaurant and a signature Asian diner by Japanese celebrity chef Nobu Matsuhisa. A choice of worldwide itineraries, most from 7 to 10 nights (but some up to 21 days), with winter favourites including The Panama Canal, Caribbean and Asia, plus Africa, South America, the South Pacific, Australia and New Zealand, and extended summer seasons in Europe and Alaska. Longer journeys include grand world voyages and transatlantic cruises. Most drinks and all gratuities included.
