It's been a while since I used it [unfortunately, the coffee house owner sold 
the business shortly after I got the wireless network running, and the new 
owner went the route I intended from the start -- completely free -- so this 
fell by the wayside pretty quickly]  However the system stores information in 
a "standard" database [mysql, postgres, etc.]  so you can review it to your 
hearts content.  The server already groups users by "realm", so building 
groups for different hotels would be trivial.

What I would suggest would be to install "freeradius" and review the 
documentation included with the install.

The freeradius server comes with a client called "radclient" -- you might be 
able to use it as-is for your application [pass it key/value pairs as stdin, 
and the program will query the server and return the results; your program 
would read these and take appropriate action]
