Thank you very much to everyone for all the info and suggestions. The wedding was tonight (Tuesday).
Ended up doing zoom, and it actually worked amazing because one of the immediate family members was stuck on another continent. I set up a big TV with a webcam (attached to a laptop,) (besides for a phone to move around), and it bridged the two sides amazingly!!! Friends on the other end made a celebration that family member, and in turn the screen became a focal point and "interactive" at times with proper dancing going on "together" in front of the screen. It joined them very nicely.
There were also other people on the zoom that were dancing in their location, and it was very nice to see that in the hall.
In the hall, there were people dancing and standing and waving in front of the screen throughout the evening. It had an amazing feel.
It was really unbelievable and really added a lot.
Picture quality was definitely low, but there wasn't necessarily reliable enough of a network that would have been able to stream high quality smoothly, so I guess you gain some and lose some.
I used my phone with a stabilizer as well for the parts away from inside the hall, and as another angle in the hall. The stabilizer is really a game changer. I was able to be dancing and be holding the stabilizer to show close up in the middle of the circle, and it was still nice and smooth.
For the music on the zoom, I attached the audio from the mixer to an interface board and attached that to the laptop, so everyone on the zoom had beautiful sound, straight from the band.
Thanks again to everyone for the help!
