The purpose of this feature is to provide a way for organizations to allow a player to book more than 1 court, but restrict them to the same timeframe for that day. This is an ideal setting for leagues or group play.

If we go to Settings > Booking Settings > Restrictions

Here we can find the setting 'Restrict All Reservations to Same Time'

This setting would be useful for groups/leagues so they can successfully block off courts for their league's playing time(s).

This is ideal if the players are the ones coordinating the league's schedule - not admin users (who can already book multiple courts during the same time).
