Be prepared to spend a good chunk of time in the Hall of Fame. It has a lot of exhibits to see and an hour and change really isn't enough to see it all. I went while in town apartment hunting and wasn't disappointed. I have my rock and roll groups that I like/ have heard of. I wish I would have had some time to check out some of the extra exhibits, but we had to be out by 1115 when we went. You get a good history and they have a pretty big collection of guitars, clothing, letters/ contracts and that sort of thing. Early during the day and during the week is a better time to go, that's for sure. It is on the pricey side ($21 for an adult) with no AAA discount which is odd! Eventually, might go back and see what I missed
Take a look at trying to get some of the extended (4hr) street parking as opposed to the garages, $1 gets you an hour of parking
