Fill in your legal last name here precisely as it's shown on your ID or passport.
This field is mandatory, which means it must be filled in.
Your legal name will not be printed on your badge, and it will not be shown in the list of
sponsors or supersponsors, but for purposes of communication with the hotel
and for insurance and security purposes we still need this information.
Your ID will be checked when you arrive at the convention.
If you want to specify middle names, please add them to the first name.
