Attractions mode configures the calendar for a run or an ongoing experience instead of a single night. Rather than building out a hold or event for every date, you set up the attraction once and it lives on the calendar as the extended booking it actually is.
Most calendars assume one date, one show. Attractions mode fits the way experience-driven venues actually work, so the team managing a multi-week or open-run booking sees it the same way they see any other date: on the same board, with the same tools, next to everything else on the calendar.
