We had a couple of questions about this so I got the scoop from Aleta:

If someone’s account has subaccounts added to them, they will be able to make purchases for themselves and/or their subaccounts at one time (see below screen shot).
 
If someone would like to purchase tickets for someone else and the friend they are purchasing for does not have a subaccount under their account, unless it is a child, they will not be able to make purchases for the other person under said persons name.  They can always purchase tickets for someone under their own name and give them to a friend.  The only time a ticket is required to be name specific is when they are requesting a refund.  The ticket name and badge name must match.  If they need to add someone to their account as a subaccount so they can make those purchases, they will need to see Customer Service.

Anyone-

  Can I get a 4-day for my 8-yr old, or do I have to wait in line each day and get one for that day only?

Thx

I believe you can, you just have to do it at the convention center.

Yes that's correct, you will only have to wait in line once for the child's badge.

Thanks !!!
