Having stayed at several Marriott's over the years, we found this to be spa like, though complete with the needs business travelers have come to expect ! We enjoyed the quiet setting, with tennis, an indoor pool, and fitness center, along with trails around the property that were especially pretty in the fall, with the changing leaves.
Massages and a pampering salon are present on site, too. A sunken bar, restaurant and fireplace lounge make for a cozy spot at the end of any day.
Going into Princeton is about a 15 minutes car ride. Highly recommend !
