Reservations – OUR HOTEL BLOCK IS CURRENTLY SOLD OUT (August 4, 2023).  We are working with the hotel to add additional room nights to our block, but there is no guarantee we will be able to do this.  There are still room nights available at the Marriott Marquis during our conference, but they are incredibly expensive and you need to book them through their general website.  We recommend searching for a nearby hotel or using AirBnB or VRBO to book a less expensive place to stay.

If we are able to get additional room nights, we will put the link to the hotel back up on the site.

Rooms can be reserved based on availability.  


Cancelation policies is 72 hours prior to arrival. Please refer to your reservation confirmation to verify your cancelation policy. If you need further assistance, call the hotel directly or contact customer service.  NAACOS does not handle any hotel reservations for participants – you need to go directly to the hotel.
