Two and half hours to tour the museum is probably a good length of time if you're an average music enthusiast. There were several interesting exhibits but at times, they would get a bit congested and you would have to wait your turn to see the displays. I thought the wardrobe area, Beatles, Elvis, and the theater shows were entertaining. Other than that, I just meandered through the halls and listened to the free concerts of student choirs and bands. To be honest, glad I went just to say I did...
