If I am under 18, can I still register?
Yes, you can purchase a Full Convention Badge if you are under 18. Your parent/guardian will also have to purchase a Full Convention Badge AND attend Brickworld with you. LEGO bricks are generally a toy for kids, and Brickworld is NOT a babysitting service. So, regardless, of your maturity level, for liability reasons, those under 18 MUST be accompanied by an adult.
Is the parent/guardian included with the paid Full Convention Badge for the minor?
No, the parent/guardian is NOT included as part of the minor badge. A separate badge must be purchased for the parent/guardian.
