In order to make an 18 hole reservation at a 9 hole facility you would:
Navigate to the Tee sheet
Open a reservation window
Add customers to the reservation
Select 18 holes instead of 9 holes (default booking product- you will see a return time when you change the reservation from 9 to 18 holes)
Save the reservation.
Two time slots will appear on the Tee Sheet.
Note: If you have an existing reservation at the return time, you will be asked to "skip conflicts and continue" to select the next available tee time.
