Crystal Cruises' two fabulous ships Crystal Serenity and Crystal Symphony top the charts comfortably in the best at sea stakes for medium-size vessels. And with her new refit, Crystal Serenity nudges out her sister for best suites at sea with clean lines, classic simplicity, and refined elegance in a dramatic ultra-contemporary remodel. Interiors of the butler-serviced, 1,345 square-feet residences have been completely reconfigured, with the dining area now closer to the floor-to-ceiling windows and the private outdoor deck, and the addition of a den/library/media room with a queen-sized sleeper sofa and closet. The master bedroom meanwhile, has been made over with luxurious bedding, curtains, two entrances, and a new seating area, and the master bath features marble, mosaics, a walk-in glass shower, and two waterproof Aquavision TV's, one embedded in the mirror, and one by the large window-side Jacuzzi tub. As well, there's a guest powder room, and most importantly a spacious living room and butler's pantry with private entrance. Who doesn't eagerly await that gentle tap on the door marking the arrival of the coat -tailed butler bearing champagne and caviar every evening.
