As both travel and gatherings become permissable, this type of event is more like the kind of event you plan all the time, but with a smaller, “socially distanced” audience.  This meeting would take place in a hotel meeting space with a full AV Production support.  There will be a live audience in the room, however smaller than normal. Additionally, there will be a good size “remote” audience beyond the one in the room, so a webcast element is necessary.  
(NOTE:  this type of event is likely the event of the near future, as it’s easy to pivot to a 100% virtual event should a quarantine situation arise again.)
