Have done Mariner and Navigator. (Doing Diamond in Jan.) Even though Mariner was a newer ship, I LOVED Navigator! You will not be disappointed! Rooms are well-appointed...very comfortable. Baths are marble (love the separate shower). Staff wonderful. Meals in Compass Rose were fabulous - wines....wonderful wines...poured freely. Casino smaller than on most ships, but staffed by friendly dealers. Pool - not overly large - but rarely used by anyone. Deck chairs very comfortable -but on our fully booked ship, sometimes at a premium. Overall -wonderful cruise - and ship.
