Stayed in three hotels lately and booked online. Two of the three emailed, one of them called, to ask if I was travelling on business. I was so no need to lie. The other didn’t contact me but gave me a sheet on arrival which said I must be travelling and staying on business and then asked for a letter from my employer. I said I didn’t have that but had an entry pass to my workplace, a well know company, in the car. Receptionist said that’s ok. So questions asked but not really much policing of it. We’re all decent hotels.
