Families favor this spot that looks like a big brick ship docked in Boston Harbor. It's close to great group outing locales like the New England Aquarium and the shops and restaurants of Quincy Market. Even the North End isn't far, if you're willing to walk a bit. Manicured Christopher Columbus Park is right outside the door, with myriad walkways and wisteria-covered archways. And then there's the Marriott's great swimming pool, overlooking the harbor, plus a huge newly renovated gym with state-of-the-art cardio and weight equipment. Rooms are decorated in cream-and-gold brocade with pillow-top mattresses, open onto a five-story atrium. Some rooms have views of the park, harbor, or the aquarium. Clean-freak alert: plush feather duvets on the beds are changed every night and allergy-friendly rooms are available. The sleek on-site Waterline Restaurant and Bar and nearby Quincy Market offers plenty of dining options.
