Secure Your Housing in Chicago

Clinical Congress 2025—one of the world’s largest educational meetings for surgeons—will take place Saturday, October 4–Tuesday, October 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.

Nearly 20 hotels are available to choose from on the onPeak website, with prices ranging from $281 to $373 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.

Using hotels in the ACS block also guarantees the lowest rates available in the city, access to ACS shuttles if the hotel is not within walking distance of McCormick Place, and protection should there be any difficulties or trouble with your room. 

The deadline for making hotel reservations via onPeak is Monday, September 15; reservations can be changed or canceled without penalty until Thursday, September 25. Additional housing details are available on the ACS website. 

Clinical Congress offers unparalleled opportunities for surgeons at every stage of their careers to learn from leading experts, explore innovative procedures and cutting-edge research, connect with peers worldwide, and acquire clinical and nonclinical knowledge and skills. Additionally, the Exhibit Hall stands out as a must-visit destination, showcasing the latest advancements in surgical technology, products, and services.
