Yes its very unreal, but the hotel owners will be getting well paid for letting the cameras have a free range of the hotel, staff and the customers who are all miked up.
When I had a pub in South London in the 70s, I let a film crew film for 3 days an advert for beer, with Windsor Davies starring as a customer getting beer froth on his large moustach.
They paid me £200 a day in hand, for the inconvenience, not bad in the 70s!
