Thanks for the info, jacob_m!! I would imagine there are many different customisations, options or add-on's to Fidelio as I have seen it on the computer screen of the Receptionist at the Executive Lounge at the London Hilton Metropole as well as at Four Seasons and Ritz-Carlton, for example. (It is very well known that FS/RC use Fidelio). Of course, the service levels are worlds apart and it seems difficult to imagine that Hilton would under-utilise their Fidelio and FS/RC would squeeze so much out of it.....
