Pros
More intimate meetings
Unlike in group-based events
there are only two people in a virtual room
Maximum connection number
If you make your event long enough,
everyone will meet everybody else
Cons
Waiting room
If there is asymmetry in attendee preferences,
some participants need to wait in a virtual lounge area
Shorter meetings
Usually there are a lot of meetings, so you need to make them short,
not to exceed the event time limit
Longer event
There are a lot of rounds, and each
virtual room
change takes time
