It was a wonderful adventure with our grandson (9)who knew if the O Museum from his reading of Treasure Hunters. Success in finding hidden doors and observing some very interesting items and hotel features.

A lot to see.... some could be overwhelmed. We found it fun and found 18 secret doors. There is memorabilia is everywhere. The history of Rosa Parks and the different collections add to the experience.
