-- A) Course statistics — counts per status, participants,

-- average occupancy, total revenue
|

-- B) Event statistics — counts, upcoming/past, registrations,
|
||||
-- average occupancy
|
||||
-- C) Booking statistics — counts, revenue, avg stay,
|

-- occupancy rate for a date range
|

-- D) Event registration counts — batch lookup replacing
|

-- N+1 JS iteration
