Go to Amex Travel website while logged in, and search for the hotels you want to see in a particular city, and then click the "search filter" to the left/bottom to look either Fine Hotels & Resorts or The Hotel Collection, or both at the same time. Only those hotels will then be listed. There's some under the "Hotel Collection", that if you book 3 nights for instance you get a free night. The free night is generally built into the price, which would be a reduced price. Some of those hotels even have their own "F&B credit", so you get that credit and the Amex Credit. However, I only saw one like that so far when searching.
