Courtyard by Marriott Faro Blanco Resort, Marathon Florida Keys

Courtyard by Marriott Faro Blanco Resort, Marathon Florida Keys

10/10 Excellent
"I did not have my itinerary from Expedia and raised an issue about the bill with the front desk. The representative explained how the discount normally applied. I believed it to be different. I found the itinerary and the representative was absolutely correct. The representative still provided me an additional credit which they did not have to do as the issue was my error. Very nice gesture by them. We have stayed at the hotel before and enjoyed our stay as always. The food we ordered at the Tiki Bar was delivered hot and was very good on each occasion we ordered. Staff was great both inside the hotel and at the pool and Tiki Bar. Great location, great service and great time. We can't wait to go back."
