most large hotels use a large switch if the wiring is already there. with large scale wifi the large units that used as hotspots set up free accounts with set time per day, they keep the user mac addy info in the system. the user laptop or device would have a set time to use the hotel system per day. if you just want hotel gust to use the system then you set up an ssid and user name. the user name change daily or how long you want to. then on the tv info screen or check in you give your gust the daily password. most of these system would be connected to a main pc that you watch your daily usage and users.
