SPARGO, Inc. is the 2017 ASCO Annual Meeting Official Hotel Reservation Agency

By making your hotel reservation through SPARGO, Inc., you can be confident you will stay in quality accommodations at a confirmed rate.

Third-party companies often illegally represent themselves as travel agencies, soliciting  attendees and exhibitors, and offering to assist them with their hotel reservations. This practice, referred to 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 often require pre-payment for rooms, but in the end do not make a hotel reservation for you. Once you realize you do not have a reservation, payment cannot be reclaimed, resulting sometimes in significant monetary loss.

These room poachers contact registrants and represent themselves as the 2017 ASCO Annual Meeting hotel reservation agency. Room poachers use a variety of tactics including

  • Distributing promotional materials that utilize the name or logo of ASCO or the 2017 ASCO Annual Meeting
  • Insisting the room(s) be reserved and/or paid for immediately
  • Offering discounted room rates below the 2017 ASCO Annual Meeting room rate

If you are contacted by anyone asking if you need a hotel room for the 2017 ASCO Annual Meeting who is not associated with SPARGO, Inc., please email with as much information regarding the poacher as possible. We appreciate your help in ending these illegal activities.
