Card terminals sit in their own PCI zone
Building systems (HVAC, locks) are isolated from the internet

Prompt used

Hotel network topology: an internet edge firewall; a guest Wi-Fi VLAN with a captive portal and client isolation; a staff VLAN for the PMS, POS workstations and back office; a separate PCI VLAN for card terminals; an IoT/building VLAN for door locks, HVAC and CCTV; and the cloud PMS reached over a site-to-site VPN.
