MacBook – Power MBP and connect Thunderbolt devices with only one cable

I think the word you are looking for is docking station.

Otherwise, if you have a spare laptop and the meetings are within the same building or VPN-enabled (i.e. on the same network as your MBP), you could just use the native OS X VNC server/client by enabling remote administration (or whatnot) in System Preferences. Then just leave your MBP hooked up, and on the remote machine, open a Finder window, hit Cmd+k, and type vnc://ip.or.hostname.of.your.mbp, and hit enter.

Alternately, if your company doesn't frown on it, you could use TeamViewer for remote access over the Internet. It has built-in proxy support if you require that, as well.

If your spare is a Windows laptop, you can install xRDP for OS X, and use Microsoft's Remote Desktop Protocol to remote into your MBP. I prefer RDP over VNC any day and use it almost exclusively on all of my *NIX machines.

No. Thunderbolt 3 doesn’t chain video, just the thunderbolt data. What protocol you are feeding to the display and the diplay size will limit your options.

For example, the LG 5k displays are thunderbolt and you get two, one on each side of the MacBook Pro. HDMI adapter might let you chain a second display from a primary display based on the quality of the hub and the resolution on both, but I am 90% certain that won’t work either. Plan on one display per physical port on the Mac.

Now, some displays will mirror the same DisplayPort stream apparently. I haven't seen this but have no reason to suspect these reports aren't 100% correct.
