The Children's Museum at Seattle Center is good for kids of all ages. It focuses on hands-on exhibits, so the kids learn while they play. The experience is a little different depending on the time of year because the museum has monthly themes and seasonal activities, but they're all very inventive. The staff are all excellent, from the educators and administrators, to the artists and performers. They also do special packages for birthdays for families who are looking for a different kind of party.
