When I checked in I was told that my room number was 4250. When my key card didn't open the door, I was told that my room number was actually 4520. It is a very long distance from room 4250 to room 4520. It was a very long walk for a 65 year old man with two bad knees. I wrote a bad review on their survey and I received an email back saying they would try to make sure that this didn't happen to someone else in the future. That is not what I would call satisfactory customer service. Especially from a Marriott Resort.
