This setting works with the Trigger Time and Trigger Window settings to determine when the action will trigger.
*"After Booking" will trigger within the selected trigger time and time window after the booking was made
*"Booking to Checkin" will trigger within the selected trigger time and time window after the booking was made until checkin.
Note '''Check-in''' requires a negative Trigger Time to set the trigger time before check-in. A positive Trigger Time will trigger that long after check-in.
