Biggest Hotels in New Hampshire

Sheraton Nashua in Nashua tops the list of biggest hotels you can book in New Hampshire through Engine, with 334 rooms, followed by DoubleTree by Hilton Manchester Downtown in Manchester (248 rooms) and Courtyard by Marriott Nashua in Nashua (239 rooms). These properties give teams and groups the room counts needed for conferences and multi-day events without splitting a group across several smaller hotels. Coordinators, assistants, and travelers booking on behalf of their organization can all use this list to find the biggest hotels in New Hampshire for their next trip.

Large-capacity hotels matter across New Hampshire because conferences, corporate events, and group travel often need dozens or hundreds of rooms held together in one place, not spread across a handful of smaller properties. New Hampshire is known for its role in early presidential primaries, its manufacturing and technology employers, and college towns that draw regular visitor traffic, all of which support demand for group travel throughout the year. The largest hotels on this list sit in different metros, from Nashua to Manchester, so organizations of every size and industry can find room blocks near where their event or business actually happens. Engine lists these properties alongside the rest of its New Hampshire inventory, and for a stay of 9 or more rooms, Engine Groups handles the booking, while smaller stays can be booked self-serve on the platform.
