We are members of the Marriott rewards program. Over the last couple of years we have enjoyed staying at the Marriott Residence Inns. We made reservations at the Marriott Residence Inn at Arundel Mills, Hanover MD(clode to BWI Thurgood Marshall Airport) on April 7, 2014 to stay there on June 10, 2014. On June 10, the date of our stay, we got an email from Debra Winkowski, Asst. Manager that our room was not available and that they could transfer our stay to a Springhill hotel. Feeling stuck and out of time, we accepted. We went to the hotel and it was not nearly as good as a Residence Inn. I work in a hotel and I know I cannot sell a room that isn't available. I think they gave our room to someone else because we were paying with Marriott Rewards points. Maybe this was an isolated action by an incompetent manager but I will find it hard to trust Marriott to honor my reservations.
