I don't see much on this--only this thread popped up when I searched.

In comparing the luxury hotel rates here vs. via Amex, a lot seem to have lower rates. I'm especially interested in the Hyde London City. The rate is the same as Expedia, except on the search page, it is listed as have free breakfast for two and a $100 incidental credit. This is the same as with Amex, but a couple of hundred cheaper overall. However, when I proceed further along the booking process, there is no mention of the extras anywhere. It's only under the "privileges" tab on the initial search page.

This doesn't give me much confidence. Does anybody have any experience booking these properties and can say if they followed through on the amenities?
