Frequently asked questions

How far in advance should I book hotel rooms for a conference in Washington?
For a large conference, start securing your guest rooms at least three to six months ahead, especially during peak congressional and association seasons in spring and fall. If you need 9 or more rooms, Engine Groups handles the room-block booking; for 8 or fewer, you can book self-serve on Engine. Early planning gives you better availability across properties and more time to finalize your event space through Engine Spaces.
What should I compare when choosing between conference hotels in Washington?
Look at the size and layout of the largest event space, the total number of meeting rooms, and guest-room capacity. For example, the Marriott Marquis Washington, DC has a largest event space of about 31,000 square feet (the Marquis Ballroom, holding up to 3,500 people) and 82 event spaces, while The Westin DC Downtown offers a largest space of about 19,000 square feet and 63 event spaces with 807 guest rooms. Also consider location relative to where attendees are flying in and whether the property fits your budget and timeline.
What amenities can conference attendees expect at these hotels?
Most properties offer on-site dining, wifi, and fitness centers, though specifics vary by hotel. Parking availability and costs differ across Washington, so confirm those details when you book. For meeting and event space itself, amenities like AV equipment, catering, and room setup are managed by the property and should be discussed when you request the venue through Engine Spaces.
What's the best way to get to Washington for a conference?
Ronald Reagan Washington National Airport is the closest to downtown and many conference hotels, with a Metro connection that makes ground transport easy. Dulles International and Baltimore/Washington International also serve the area if you're coordinating arrivals from multiple regions. Staying near your event venue simplifies logistics; properties like the Washington Marriott Wardman Park (69 event spaces, largest about 36,000 square feet) are accessible by Metro and close to key districts.
How does billing work when I book rooms for a large conference?
Engine offers consolidated invoicing for multi-room bookings, so you're not chasing receipts from every traveler. You can choose from multiple payment options, and there's no membership fee to use the platform. For a stay of 9 or more rooms, Engine Groups handles the room block; for 8 or fewer, booking is self-serve.
