At Newport Marriott Hotel & Spa, you'll be just a 5-minute drive from Thames Street and Newport Mansions. Guests can visit the spa to be pampered with deep-tissue massages, body wraps, or facials, and MainSail, one of 2 restaurants, serves American cuisine and is open for breakfast, lunch, and dinner. An indoor pool, a bar/lounge, and a fitness center are other highlights. The helpful staff and location get great marks from fellow travelers.
