Book Your Hotel in Chicago for Clinical Congress 2025

Clinical Congress 2025—one of the world’s largest educational meetings for surgeons—will take place October 4–7 in Chicago, Illinois. The meeting will feature the latest offerings in surgical research and education for today’s busy practicing surgeons and surgical team members.

For those who are planning to attend the meeting in person, hotel reservations are now being accepted through onPeak, the official housing provider for the ACS. Booking ahead offers the peace of mind that comes with securing a preferred room at the best price, and what’s more—there’s no upfront cost for reserving a room online today.

More than 20 hotels are available to choose from on the onPeak website, with prices ranging from $281 to $480 a night. Booking through onPeak allows attendees to collect rewards points for hotel loyalty programs, and every reservation made through the website supports the ACS’s ability to negotiate the best rates available for attendees. Plus, if you make a reservation by September 15, 2025, you will be entered into a Suite Upgrade Raffle for your 2025 hotel stay.

Reservations can be changed or canceled without penalty until September 25, 2025.

Registration for Clinical Congress 2025—which is expected to be a hybrid event (held onsite and virtually)—will open next spring.
