We do group tours and would like to allow one person to register their entire family, without having to register each person individually, while still following a maximum participant rule.
For Example: We can have 40 people in a group. We would like when a family registers they enter the information (name, email, etc.) once, then indicate 5 people attending. This would reduce the available slots in the group reservation from 40 to 35. The next family would indicate 2 people and the available slots would reduce by two to 33. In each case, the family only had to enter information once.
