To clarify, he was a registered guest. That doesn't make him a paying guest. The tourist was the paying guest who registered him as one of the occupants of the room. As MissBlue said, the registering of the Jamaican BF/GF is common. Trying to legislate who can come in & who can't might sound like a "good" idea but is totally unrealistic &, as the many comments show, is just not right or workable.

NBCC is known as being friendly & open to all. That is one of the many reasons they have a great reputation & are in demand. To discriminate against all to weed out a few bad seeds not a good policy. Signing in visitors/non-registered persons is the best any hotel can do.
