I was there Friday and thought it was quite good. Compared to the two others I've been to (Boston and Norwalk), there were far fewer passenger belongings, and far more china, crystal, etc., items. There were also recreations of the grand staircase, a first-class corridor and stateroom, a third-class cabin and a watertight door, none of which were in the other exhibits that I recall. Well worth a visit.
I enjoyed the exhibition in Philly, yet wished I could've gotten a photo of the lifeboat davit there. It was such an amazing artifact to see - I just assumed as well it was the davit between the first two boats on the port side because of their position. I did find some photos of the exhibition and they are posted on my site.
