Did you know that you can setup a different amount for deposits required to secure a booking, based on number of Adults & Children? (the definition of until what age a guest is a child is entirely up to you and should be part of your terms and conditions).
This option is very useful, particularly if you offer set menus and can be link to pre-ordering, where the host selects whether the pre-order is for an adult or a child.
When setting up your deposit rule, tick the box: Tick to add multiple price options. (only applicable for 'Pay per guest' and 'Charge Upfront' settings)
You can then add as many options a required for that rule.
This will be displayed to the guest before the payment stage for both web bookings and telephone bookings:
If the numbers entered by the guest differ from the total number of guests for that booking, the system will notify the guest prior to moving to the next stage (Payment screen).
