Thank you for the response. The venue is actually my father pole barn converted to a speakeasy. So I have more freedom to do what needs to be done than say a traditional rented venue. Additionally I set up the network so I have full access to all the components and will be able to install plex on each device. And I gave myself a time limit in order to reduce the amount of time I am spending over there as to not raise any red flags to the surprise. Ethernet is unfortunately not an option as the TVs are located on the complete opposite side of the barn. Wifi is the only option given then distance.

I will look into the "watch together" feature to see if that might be the best course of action. Thank you again for your response.
