One adult (parent/guardian preferred) in your family creates an account that will be used to register everyone in your household.
Add all the people in your family to your account that need to register for a conference (adults and children).
Basic information like their name, gender, birthday, allergies, etc are collected and saved to make registering for future conferences faster.
Register one or more of the people in your account for a conference.
Make on online payment with a credit card or debit card.
