The ability to add an event directly from our website, without having to go through another site or app; it's easy to use! I wish there was more options when adding multiple locations/cities at once so that we could have all available dates listed in one place rather than going back-and forth between two separate calendars. It would be great if you were able to select which date range your users are allowed access too (ie - only allow them access during working hours). This allows us to keep track of who has been granted permission vs those still waiting approval.
