Simply email NADO’s Events Manager at [email protected] with your request to cancel along with your reservation confirmation number. Before the reservation is transferred to someone else, your original profile and billing information will be deleted; and a cancellation confirmation email will be sent.

In the email, please include the guest’s full name, email address, and check-in & out dates. If there is an existing reservation associated with the request, also provide the hotel confirmation number.

Rooms will begin to free up as cancellations come in over the next two weeks. We are working down the waitlist and will modify/add reservations as rooms become available. Unfortunately, we cannot guarantee a reservation for everyone but are hopeful we will be able to accommodate most.

If you have a room at a nearby hotel and you get a room at the conference hotel, you can easily cancel the back-up reservation before the 48–72-hour cancellation deadline at no penalty.
