Hi - again, from your comments and suggestions, this evening, we've added a request for your customers to advise you of how many adults and children are in their booking, on the personal details screen of the customer booking form.
This does not have any connection to the rates given on the previous customer booking page, and it is purely for your information. How you define adults and children could be added to your website, or you could add it to the Personal Details Screen Text, in the Emails & Notes section.
