Not sure if you talked to the FD at the CY, but our did your own research.
Ultimate Reservation Guarantee
If for some reason we’re unable to honor your reservation, we’ll pay for your accommodations that night at a nearby hotel and compensate you for the inconvenience. To be eligible, you must provide your Marriott Rewards membership number when making a reservation. Compensation varies by hotel brand. [ALL LEVELS]
You are also entitled to $100. Only Platinums get 90,000 points for being walked from a Courtyard.
Guaranteed Room Type
When making a reservation, be sure to note both your Marriott Rewards membership number and room/bed preferences. At locations throughout the U.S. and Canada, we'll always honor your bed type request. Outside U.S. and Canada, smoking/nonsmoking preferences are honored based on availability; exact bed sizes may vary. If guarantee is not met, guest compensation applies. [GOLD/PLATINUM]
At Fairfield Inn the compensation is only $25. I don't believe you will be able to collect both.
Let us know how you make out.
