The term "flagship" is reserved for the standard bearer of the line, the best of the best as evidenced in the elegant ms Rotterdam. Everywhere, premium pervades. Spacious staterooms, a full 80% of them, offer expansive ocean views. (Guests staying in Penthouse or Deluxe Verandah Suites have exclusive use of the Neptune Lounge and its attentive concierge.) An intimate reservations-only restaurant features the cuisine of the Pacific Northwest. There's an expanded spa, duty-free shops, intriguing art. And in the soaring atrium lobby, a fanciful clock tower announces 14 world times as the ms Rotterdam explores the planet's special places.
