DailyThemeScheduleSync
struct DailyThemeScheduleSyncComputes the differences between the DailyTheme table and the theme days found in the Event schedule.
Theme days in the schedule are events whose title begins with “Theme:” (e.g. “Theme: Cosplay Day”). The remainder of the title becomes the theme’s title and the event description becomes the theme’s info. Themes are matched to events by cruise day.
