This could be why the OP asked specifically about Hilton. Hilton Honors allows a perk that the spouse stays free in the same room. In the US the cost is usually per room and not per person. In other parts of the world that may not be the case, as in the UK.
So when you book a room in the UK as a Hilton Honors member, you book the room rate for one person and that's what you pay even if it is the cheapest single person rate. You then need to make sure the hotel knows your spouse will be staying with you, per Hilton Honors, and the need to provide a double room.
