It s possible, sure. Just depends on the hotel. Most chains allow the manager a room but as far as other employees - probably not. Need to find a Mom and Pop hotel.Good luck.
More so motels have what you call live-in quarters for those who are employed there. As for hotels, this factor is less available...It s just up to the owner/owners. I don t know if this counts, but I once remodeled a hotel in my past was able to live there for the 2 1/2 months of time it took to complete the job.
