Hello @jrab66 , i would suggest the introduction of vlans. I was jn similar situation in a school, and introduction of vlans and it was a pleasure, you may have to do a bit of planing. But, maybe @alefattorini could direct you to the right people, the commercial version of NETHSERVER can and is developed for hospitality industry.
Otherwise just message me and i can send you more and maybe even assist you.
