Hilton HHonors lists this benefit: http://hhonors1.hilton.com/en_US/hh/about/benefits.do Spouse stays free Spouse stays free in the member's room on qualifying stays. This benefit excludes stays at Hampton Inn properties. This benefit does not apply at any hotel when the rate includes additional components (e.g., meals, activities, parking, etc.) that are quoted as a per person or per room charge. I am looking at booking a stay in Vienna for me and my wife where the best rate is: GREAT GETAWAY W/ BRK NON-REFUNDABLE. NO CHANGES OR CANCELLATIONS. 7-DAY ADVANCE PURCHASE. SOME EXCEPTIONS. If I choose two people for the room, the rate is 6 Euros higher than if I just choose one (my normal choice). I am HHonors Gold, so I don't actually care about the breakfast rate as I'd get it anyway, but even with breakfast this rate is significantly better than the regular prepaid rate. So... since the breakfast isn't spelled out as a separate per room or per person charge, should I assume that the front desk won't give me trouble when I book for one person and show up with my wife?
