Registrations received after March 23, 2026, will be charged the last-minute registration fee.
On-site registration will be available on a space available basis. Please keep in mind that if the congress is sold out, we will be unable to accept onsite or last-minute registrations. In order to reduce the chance of disappointment and frustration (if you have not pre-registered) we recommend that you carefully check the website and check Congress availability before traveling to Napa.
