This fairly new (newly relocated and updated) museum is now in the general Space Needle, Chihuly, EMP area and should be added to your must-see list. We went there while visiting relatives in Bellevue, WA and I recommend it for natives and tourists alike. Seattle's history is presented using many different media techniques and most of it is done so that a range of age groups will learn and enjoy. The modern era highlights not just Seattle industry but also its social history. There are several floors to explore and I agree with previous reviewers to allow at least two hours to enjoy. Young children (kindergarten through about 3rd grade) won't get much out of this. The museum has provided a play area for them on the first floor so you need to plan for someone in your group to stay there and play with that child. There are discounts for seniors and children under 14, which we appreciated.
