Yes. Masks will be required at all times while in the convention room. We will also enforce any federal health mandates, as well as those issued by the State of Colorado or the City and County of Denver, or any policies set by our hotel.
Acceptable masks include N95/KN95 respirators (or equivalent international standard as described here), and surgical masks. Masks must cover the nose and mouth fully. Masks must not have holes or exhalation valves. Cloth masks, gaiters, bandanas, mesh masks, costume masks, etc. are not permitted.
