BeatCal's experience seems to echo mine to an extent.

Over the past couple months the FS hotels I've stayed in have met my profile requests (pretty basic--Bvlgari White Tea and plates/cutlery in my room) without any follow-up in my end. Additionally, a FS I'll be staying at next week mentioned in a pre-arrival email that all my preferences were noted.

Something I really like is that many FS's have been very flexible with swapping out complimentary amenities. While I like, for example, a daily fruit basket from time to time, I don't have much need for it when my breakfast is already inclusive. Four Seasons is very good about offering up an amenity as a gesture than I can really utilize and appreciate depending on the circumstances unique to each stay.
