American College Of Surgeons - Inspiring Quality: Highest Standards, Better Outcomes

Hotel Accommodations

Support ACS by booking your room through onPeak at one of the official Clinical Congress Hotels!

To obtain the necessary amount of meeting and exhibit space at the convention center and surrounding hotels, ACS must commit to a minimum number of guest rooms. If that commitment is not met, ACS will incur significant financial penalties and have difficulty obtaining sufficient meeting space in the future. This can have a major impact on the programs that ACS is able to offer to you at Clinical Congress. You can help ACS avoid penalties by booking your reservation through the official housing company, onPeak.

Top reasons why you should reserve your hotel rooms via the ACS housing system:

  • Lowest rates. We’ve secured over 35 hotels in the heart of the city offering a wide range of options, price points, and the lowest rates possible.
  • Flexible terms. Book today, and have the flexibility to change or cancel your reservation without charge up to 72 hours prior to arrival.

  • Support ACS. When you book through our system, you are supporting your organization’s ability to provide quality education in appealing destinations.
  • Free transportation. Complimentary shuttle bus service is available between most* ACS-contracted hotels and the San Diego Convention Center.
