Registration and Hotel Reservations are now open for the 2018 ASCO Annual Meeting. The Hotel Reservation and Early Registration Deadline was Wednesday, April 25, 2018, at 11:59 PM (EDT)

Online registrations and hotel reservations are processed securely and confirmed immediately by email. Registrations and hotel reservations cannot be accepted by telephone, mail, or fax.

Meeting sessions will be held at McCormick Place. 

Save money by sharing a hotel room at the 2018 Annual Meeting. Connect with other attendees who are interested in sharing a hotel room via the Find a Colleague directory. Update your profile with the “Interested in Hotel Room Share” tag to denote your interest in sharing a room. Meeting attendees can search for profiles tagged as “Interested in Hotel Room Share” with the ability to immediately message those colleagues.

Use of the Find a Colleague directory, including searching for attendees and sharing a hotel room is subject to the Terms of Use. Use your best judgment and take precautions for your safety.  ASCO is not responsible for the safety or security of attendees using the roommate feature of the Find a Colleague directory.  


Third-party companies illegally represent themselves as travel agencies, soliciting attendees and exhibitors, and offering to assist them with their hotel reservations. This practice, known as "room poaching", can have serious consequences, including higher room rates, non-existent reservations at check-in, loss of pre-payment, or sub-standard hotel accommodations.

Room poachers require pre-payment for rooms but do not make a hotel reservation for you. Payment cannot be reclaimed, resulting in significant monetary loss.

Room poachers contact registrants and represent themselves as the Meeting hotel reservation agency, using a variety of tactics, including

  • Distributing promotional materials that utilize the name or logo of the Meeting
  • Insisting rooms be reserved and/or paid for immediately
  • Offering discounted room rates below the Meeting room rate

If you are contacted by anyone who is not with SPARGO, Inc., please email SPARGO with as much information regarding the poacher as possible.
