2 hrs MAX
As long as you like. It's boring to us. Not alot to visit, inside the museum.
I was there about 45 minutes. Just depends on how much you want to do.
We were inside about 3 hours and then went out back and explored for about another hour. My kids are 12 & 14. We were with friends whose kids are 10 & 12.
If just looking at the free admission part probably an hour. If you do the paid admission Discovery Room, exhibits, virtual reality, etc I would plan 3-4 hours. I have 4 kids between 7-13 years and we had to leave after 3 hours for an appointment but they could have easily explored for another hour or two.
Between 45 minutes and 2 hours unless you really get into creating the dinosaurs that interact with you onscreen
Plan on at least 2-4 hours depending on how old your kids are. They have so many different things to see and lots of hands on activities.
