TOPIC:

Hybrid meetings essentially have two locations: One in the real world and the other on Zoom (or some other video conferencing tool)

Thus It is important to have two types of RVSP so that people can indicate who will be at the physical location and who will be in the zoom location.  This will help us have a head count of who will be there in person as well as distinguish who will be there in zoom.

Also, Since there are two locations, I think there should be an option to specify both locations.  Currently you are allowed to pick one location but I think it would be good to pick two locations to meet on the agenda.

if this gets implemented, {{nextmtgvenuename}} and related variables would need to accommodate with something like {{nextmtgvenuename2}}

So enter the address for the physical venue and then enter the Zoom URL in the URL box.   

I just think you are making this more complicated than it really is.
