    ADCES22 is a premier event, and there are unscrupulous companies using the meeting to make false offers of registration and housing reservations. You may receive advertisements, e-mails or phone calls from these companies. Registration and housing should only be accessed from the ADCES main website,

    Please note that MCI USA Events is the official housing provider for ADCES22. ADCES has been made aware of pirate housing companies (unofficial housing companies) that may be pursuing ADCES attendees to book their rooms at supposedly significant discounts. These companies are not authorized to represent ADCES, nor do they have access to officially contracted room blocks or rates on behalf of the organization.

    For your own protection, please do not make reservations through any other housing companies. If you receive a call or email from any company that is not the ADCES' official housing provider, MCI USA Events, please email or
