I had a reservation for me and my S.O. at a hotel booked through booking.com (priceline), but we were denied access to our room since we were 2 people, and the reservation was for a single. Does any one know what if anything governs the ability of hotel owners to limit the number of people in a hotel room? The hotel kept the payment since they consider this a cancellation. Am I S.O.L?

To make things slightly more confusion, somewhere in the T&C of priceline, they state "Your rooms are guaranteed for double occupancy. " though I am guessing now they meant this to refer to the name-your-own-price option.
