Below is a copy & paste of the T&C. I bolded the parts that probably answer your question.

Fine Hotels + Resorts®
Fine Hotels + Resorts® program benefits are available for new bookings made through American Express Travel with participating properties and are valid only for eligible U.S. Consumer, Business, and Corporate Platinum Card® Members and Centurion® Members (Delta SkyMiles® Platinum Card Members are not eligible). Bookings must be made using an eligible Card and must be paid using that Card, or another American Express® Card, in the eligible Card Member's name, and that Card Member must be traveling on the itinerary booked. The average total value of the program benefits is based on prior-year bookings for stays of two nights; the actual value varies. Noon check-in and room upgrade are subject to availability and are provided at check-in; certain room categories are not eligible for upgrade. The type of experience credit and daily breakfast (for two) varies by property; the experience credit will be applied to eligible charges up to the amount of the experience credit. Advance reservations are recommended for certain experience credits. If the cost of Wi-Fi is included in a mandatory property fee, a daily credit of that amount will be applied at check-out. Benefits are applied per room, per stay (with a three-room limit per stay); back-to-back stays within a 24-hour period at the same property are considered one stay. Benefit restrictions vary by property. Benefits cannot be redeemed for cash and are not combinable with other offers unless indicated. Benefits must be used during the stay booked. Any credits applicable are applied at check-out in USD or the local currency equivalent. Benefits, participating properties, and availability and amenities at those properties are subject to change.
