The Wentworth by the Sea Marriott Resort http://www.wentworth.com/ in New Hampshire is a great resort hotel location with many wonderful activities in the area. A family favorite in the area is Hampton Beach, which is a few miles away with fun for all interests.
I have stayed at this property with my family, on business, and for an anniversary weekend with my wife. All separate purposes provided delightful stays.
Wentworth-by-the-Sea is amazing. We were there for the Winter Wine Festival 2009 and stayed in the Admiral Suite, the duplex loft suite in the center turret with 360 views. Then, for Memorial Day 2009 all expectations were exceeded again in the duplex villa of the Little Harbor Suites overlooking the Marina. The accomodations, the dining, the Concierge Lounge and the associates we encountered were amazing.
