For those asking if they can “bring someone”, I would surmise based on the link sent to us that each person needs to fill out their own registration due to limited space.
Note the section titled “Can I bring a friend and/or my child(ren)?” 
That is indeed correct, @AnthonyM_1 . The FAQ is on the same website that was emailed to everyone to announce the Google-hosted meet-ups where folks registered for events.
I’m looking forward to hosting my meet-ups!
