*Beware of Housing Scam

Several non-official housing companies have been contacting SSO speakers, exhibitors and attendees claiming they can secure hotel rooms at designated SSO hotels in Seattle for the Annual Cancer Symposium. These companies are not authorized to represent SSO nor do they have access to officially contract SSO hotel room blocks or rates in Seattle. If you receive a call, please be aware that there have been reports from groups and individuals after paying these companies that no room was reserved, and they lost their money.

Please do not make reservations through any unknown housing or travel company. The official hotel reservation or housing service company for SSO is SPARGO, Inc., 11208 Waples Mill Rd., Suite 112, Fairfax, Virginia 22030. Hotel reservations for the SSO Annual Cancer Symposium can be made online via the SSO 2017 website.
