It's not like walking a normal museum. The exhibits are all interactive. You could spend hours just playing in one area. Or you could power through in probably an hour easy.
Me my girl and 2 of my kid (7 and 9 years old) stayed there for about 2 hours and only seen half
if walking to long is hard for u. they have wheel chairs by the main rest room u can use for free
Plan for a whole day. We spent probably 5 or 6 hours there, and the only reason we left when we did is our 4 year old was getting cranky from not having a nap.
That depends on how much you stopped by each exhibit 4-5 hours is average that my nieces and I spend there.
