I saw that at the newly added SLH property in Manhattan WestHouse you do not earn Hilton points or receive any Hilton benefits if you book directly with them. The Hilton website rate for dates I checked have a base rate of $674 per night, but their own website has the same Luxury King room base rate for $477.37 for the same dates. Personally, I would not want to stay at a property that would not have the backing of Hilton in the event of any issue. Apparently the Hilton lowest rate guarantee does not apply. If you book directly, you are on your own.
