it was our first time at the rock & roll hall of fame. we purchased tickets online and though there were a lot of people inside (it was a saturday AND a holiday weekend), the lines for tickets were moving fast. once inside, there was enough space for everyone, even little ones, to be able to walk freely and at a comfortable space - without having to bump into people. the displays were nice in the sense that there were sections that let you listen to music, some that show off costumes the artists wore, some memorabilia, even furniture they wrote music on. the best was just learning about the the history of the artists and the evolution of rock & roll.
PS: the gift shop was not shabby at all and the cafe served great, hot food.
