American Express Membership Rewards - Can Amex FHR take breakfast bennie day of arrival?

Arriving into an FHR property (BKK Pen) around 9am, and will be leaving the next day too early to grab breakfast. Does anyone have any experience taking it on that morning as opposed to the breakfast after the reserved night? Should this pose a problem?

Are you paying for one night or two? If you're only paying for one night, you could ask, but I would say that the hotel is being pretty generous allowing you such an early check-in in any case, so I'd not complain too much if rebuffed. On the other hand, if you're paying for two nights, it's pretty clear you should be able to get breakfast.
