HPG 2024 will be held in the Studio Loft of the Ellie Caulkins Opera House, in the Arts Complex of Denver, Colorado. This is adjacent to the Colorado Convention Center, the venue for SIGGRAPH 2024.
The entrance to the Studio Loft is on 14th Street, near Champa Street.
The Arts Complex web site has information on parking and other transportation options for the venue.
HPG does not have any direct arrangements with hotels, but there are many hotels within walking distance of the conference venue. Note that the venue is immediately adjacent to the Colorado Convention Center that is hosting SIGGRAPH, so the SIGGRAPH hotel booking system should also have you covered if you are attending both conferences.
