Child Policies are new in Jomres 9.23.0 and are available if you use the Standard tariff editing mode.
The Child Policies page allows you to set prices for different ages of children, plus the option to apply these prices either Per Child Per night, or Per Child Per stay.
Prices configured here are applied the same, regardless of the value of the rooms chosen.
To create a new set of prices for an age range, click the New button.
Once you do that you can set the age ranges covered for this price (rate field) and how they're charged.
Important : Make sure that age ranges here do not overlap, so 0 - 3, 4-13 , 14 - 17 is correct, 0 - 3, 3 - 13 would not be.
Child rates set to Zero will be treated as free.
You can easily enable/disable child rates in Property Configuration > Booking form tab. If you set the "Do you accept children under 18 years of age?" to No then they will not appear in the booking form.
