The opportunity is to procure 2 seats with your registration, yourself, plus an AHA member guest.
Almost the same as last year. The new part is that your guest must be an AHA member.
Last year all registrations required a name, the same this year. This year all names require a unique AHA member number. (same change as above)
What you cannot do is to register for yourself and a guest, and have your "guest" register for her/himself and you.
Does that make sense to you?
