There is so much to see that it is difficult to see it all in two days! If you only have two hours you can only see a very small amount of everything that is there. I certainly would not go if I only had two hours.
2 hours... maybe if you are a marathon runner
All day... Very big
You can spend days exploring. 250 acres of displays. 2 hours would be just enough to get acclimated. You need at least 2 days and still not see everything!
