SPARGO, Inc. is the ASCO Oncology Practice Conference Official Hotel Reservation Agency

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 Conference hotel reservation agency, using a variety of tactics, including

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