No way would I stay at this hotel. I don't believe in staying at hotels that wire their buildings in MC cable. For me, it's got to be E.M.T.
You apparently do not get out much.
Many (most) Hotels (outside of a few large metropolitan areas) will be MC and many will be NM.
Can I ask how you choose where to stay?
The buildings wiring method is not usually something I would expect the reservation clerk to know about.
