Hotel and Travel

Official Housing Block

The AAO-HNSF negotiates reduced rates rooms at a selection of Philadelphia hotels and uses a reservation booking site powered by MCI USA Housing. We encourage you to book early to ensure you get your first-choice hotel and access. Staying in the official hotel block offers convenience, amenities, and free shuttle service to the convention center (unless the hotel is within walking distance). Reservations are available on a first-come, first-served basis.

If you need assistance booking your hotel, please reach out to MCI at 866-212-0683 or [email protected]. Their call center hours are 8:00 am – 5:00 pm (CT), Monday-Friday.

Beware of Unauthorized Hotel Solicitations

Please note that MCI is our official housing partner for the Annual Meeting. They will not solicit you to make a reservation at any time. While other hotel resellers may contact you offering housing for your trip, they are not endorsed by or affiliated with the Annual Meeting. Beware that entering into financial agreements with non-endorsed companies can have costly consequences.
