It's a small 2nd floor studio apartment turned into a shrine of 9/11 photos and artifacts. If you use the handheld tourmate for all the items, it can easily take up the two hour time frame. You can leave earlier though. Do not arrive earlier than your ticket time. They won't let you in. We were there five minutes before our tour and we had to wait outside. I would only recommend this museum for somebody who is really interested in the recovery efforts that followed 9/11.
