Then that hotel is likely as old as the hills, and obviously there are edge case scenarios where this won''t work or be financially ... tricky. In Australia almost all sparkies/data cablers changed over to using Cat5 for telco cabling decades ago as it was way cheaper then cat3 a long time ago.
Like i said there will be edge cases where it is more a financial decision, sometimes its better to bite the bullet and just wear the cost of new stuff as opposed to maintaining legacy gear, that is a decision every business has to make at some point in time. I still think that short of the cabling issues your going to waste more money on legacy half options over time then just doing it right and cabling for the future....
