3 hrs
It is interactive. If you go around and let your child play in the exhibitions it should be about 3 hours, if you add a visit to the IMAX then you would have to add the length of the movie.
Like two hours or more time it depends if youre going with children
You could easily spend 3 to 4 hours here, a couple more if you catch one of the movies playing at the IMAX theater...
