The 'gift' of a free night's stay is to make up for the hotel industry not having any rooms left on Christmas Eve over 2000 years ago when the original 'Mary and Joseph' had to settle for the night in a stable.
... A free car-parking space will (also) be provided for the donkey ... The couple can stay anytime from Christmas Eve to the Twelfth Night."
