lol. Most famous people use another name....all celebrities do. It is to ensure us little people don’t know they are staying at the same hotel. (As if most of us could afford it anyway).
My company always objected to having our name on the hotel's "Meetings" board in the lobby we were holding our sales meeting.
Many competitors lurk.
So we'd come up with a fictional name every day. My favorite was Larry's Tire and Wheel Co.
