Actually they are not exhibits. It is called museum but are children interactive activities for fun and learn. Parents can go but children have fun.
You can visit for 2-3 hours and see everything, but if you want to spend extra time in any of your child's favorite areas then you could certainly spend longer! You can also come for just an hour if you only visit a few of your favorite exhibits.
Below, James makes a great point. The Museum closes every day with a parade at 4:45 (on the weekdays) and 5:45 (on Saturday).
We were there 3-4 hours
If you've got patience and your kids enjoy playing and dressing up, then you can spend a whole day here. We were there for 5+ hours and left at closing time.
Up to 3 hours. They have a subway if you get hungry as well :)
