We have a minimum age of 25, so if the lead guest age is not displayed, or their date of birth is not shown, then we have no way to check whether they are over 25 years old. We have 2 guests checking in today that we have had to speak with and one we had to cancel as she was only 19 (even though she ticked the box to say she was over 25). This would be very helpful as a quick glance to see how old the lead guest is and to see if they are eligible or not to stay.
