Save money by sharing a hotel room at the 2019 ASCO-SITC Clinical Immuno-Oncology Symposium: Connect with other attendees who are interested in sharing a hotel room via the Find a Colleague directory. When the Directory opens later this year, 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.
