FCO Courtyard 2008. 10 PM Check-in after a long day of driving from northern Italy. Enter first room: Occupied. Back to front desk for new room assignment after saying YES to the question: "Are you sure it was occupied?" Enter second room: Occupied. Back to front desk to repeat the first conversation and to get another new room assignment. We insist that a manager check the third room before it's assigned to us. Third time was a charm.
From Marriott on site: Some "oops" statements but nothing more. We were glad finally to get a room ready for us and then headed to bar.
