How long does it take to tour

I'd allow at least 4 hours. Save the plaques for last.

So long as you want. We spent about 4 hours, with a break for lunch, and did not read all information or watch all videos.

We were there for three hours and it wasn't nearly enough. We plan on returning in the not too distant future and allowing at least six hours. But we're a little nerdy when it comes to baseball and it's history.

Depends on how long you take it in. Its typically a self guided tour. We spent 2 hours going through it.
