How much time do people usually spend at the museum?

We had four adults and we spent about three hours.

We spent about 2 hours in the air museum, went to lunch at The Diner down the street. Went to the space museum and spent at least 3 hours there! My grandparents age 11 and 8 loved it!!! My favorite was the space museum!!

Depends on your love for Aviation and curiosity, it could be an all day event, its an amazing place.

There were 2 adults in our group and we also spent 3 hours there

We have a toddler and s 2 month old and we spent about 3 hours total there.
