Planning on coming there today since family is coming from out of town. How much time do you think this would require?

I'd say about 2 to 3 hours. I don't know, It's been a long time since I've been here.

Plan on spending at least a couple of hours. It has amazing displays !

I did this tour with my son (11) in two hours. Maybe 2.5. Anyway, it's worth the trip, but it is out dated. If you love trains, it is a spectical....

Definitely a few hours,

Thanks for reaching out Well you may come and visit with in time frame hours 10am to 6pm.

At least two hours if you really want to see everything. It's a LOT bigger than it looks!

It's pretty big there and there is a lot of detail. I would suggest a few hours (2-3) depending on young ones and if you want to take the train ride or not.

3 to 4 hours in honestly if you love trains 6 hours at least
