This guidance should be applied beyond traditional events if the business in question does not clearly fit into any other guidance category. For example, escape rooms do not clearly fit into any one business sector, so they should follow guidance for unseated indoor events. Other examples include arcades, wedding receptions, large-scale trade shows, and museums.
Cliff Palace and Balcony House are ancient cliff dwellings that the ancestral Pueblo Indians inhabited in the 12th and 13th centuries. Located in Mesa Verde National Park, both are World Heritage Sites and National Monuments. Balcony House had forty-five rooms and two kivas (ovens), and it can only be accessed on ranger-guided tours. Tour participants must climb a thirty-two foot ladder and then crawl through a twelve-foot tunnel to access Balcony House.
