Wedding DJ at Westfields Marriott Washington Dulles in Chantilly, VA

The Space

The Westfields Marriott Washington Dulles sits on 26 acres near Washington Dulles International Airport, built in a Federalist-style within the Westfields Corporate Center Business Park, which gives the hotel a formal, established look rather than a glassy modern high-rise feel. The property is large enough to function as both a hotel and a conference destination, with the two roles built to run side by side rather than one squeezed into the other.

At the center of it is a 60,000-square-foot conference center that includes one of Northern Virginia’s largest ballrooms, part of a broader total of 31 event venues offering 40,000 square feet of flexible meeting and event space across the property. A couple choosing this venue for a wedding is choosing a hotel built around hosting large events as its core business, not as an occasional side use.

Capacity & Layout

The property can accommodate up to 500 guests across its ballrooms and terrace, a figure that puts it comfortably in range for a large wedding, and with 31 separate event venues to choose from, a couple has real flexibility in matching room size to guest count rather than being locked into one fixed ballroom. That range also means a rehearsal dinner, ceremony, and reception can each be assigned their own space within the same property.

With 336 guest rooms on site, out-of-town guests can book their stay in the same building as the reception, cutting out a drive between hotel and venue entirely. Rooms run about 400 square feet with separate sleeping and living areas, giving guests real space to settle in for a multi-day wedding weekend rather than a cramped overnight stay.

Amenities

Guests have access to both indoor and outdoor pools along with a 24-hour fitness center, useful for a wedding weekend that stretches across more than one day, and outdoor tennis and pickleball courts, managed in partnership with JTCC Chantilly, give guests something active to do between events. Wellington’s Restaurant, serving American cuisine, is on site as well, so there is a dedicated dining option beyond the wedding’s own catering.

We have worked events here more than once, and the scale of the property is real: a 60,000-square-foot conference center, one of the region’s largest ballrooms, and enough flexible meeting space to run a rehearsal dinner, a ceremony, and a reception without ever leaving the building. For a couple planning a full wedding weekend rather than a single-day event, that self-contained scale is the main draw.

Location & Getting There

The hotel sits in Chantilly, Virginia, close enough to Washington Dulles International Airport to make travel simple for out-of-town guests and family flying in, while the 26-acre property itself is described as a tranquil setting, set apart from the airport despite the short distance. Its location within the Westfields Corporate Center Business Park puts it near other business and travel infrastructure without sacrificing the grounds’ quieter feel.

In a ballroom of this scale, sound has real room to fill: with one of Northern Virginia’s largest ballrooms, hard hotel-standard flooring, and a soaring ceiling built for large events, a DJ’s system can be positioned to cover a full 500-guest crowd cleanly, while the property’s smaller event venues, sized for more intimate ceremonies or cocktail hours, call for a scaled-down setup suited to a tighter room.
