Hampton Inn is the only Hilton brand offering a 100% guarantee that I am aware of.

Had an interesting scenario happen today with my parents, who (like me) are HH Gold members. They booked a room with a specific bed type for a weekend stay at a suburban Washington DC Homewood Suites months ago. They arrived tonight around 6 (so not a late arrival) only to be told there were no rooms available for them. The explanation was that specific room types were given out on a “First come first serve” basis at check in, even if a reservation existed. They were offered a room with different beds than they wanted. Eventually the hotel did offer them their bed type in a “downgraded” room (assuming a studio instead of a 1 bedroom suite) and a discount off the rate.

We’ve certainly run into situations when booking a room where a bed type isn’t available but I’ve never heard of reserved room types not being honored at check in because other people had arrived before them and taken the rooms. If it’s a maintenance issue, I surmise they would have been told such. Anyone else have this happen to them?
