Some people can buzz through in about 30 or 40 minutes if they are just glancing and not stop. We spent about 2 hrs with our boys and that was without reading everything or interacting with everything. I would say you could easily spend 2-3 hrs minimum.
1-2 hours, did kids scavenger hunt took pictures.
We were there for over an hour, taking a lot of pics, but if you walk through it quickly, it can be as fast as 20 min. It's not a big place, but it is beautiful!
We were there 1 hour and some change with lots of pictures
