There's nothing scary about these nights at the museum. The first weekend features aerial performances on the premises and in its gardens by Italian group Studio Festi who have performed at the opening ceremony of the 2006 Winter Olympics in Turin.

If your kids are the the kind who fight for their right to party into the night, the National Museum and other museums including the ACM and SAM will offer free admission to the public on July 25 till 2am. I'd think this one was more to draw the teenagers in, though there are a couple of younger child friendly activities from 6pm - 10pm including open-air screenings of the original 1971 film adaptation of Willy Wonka and the Chocolate Factory and Hairspray.

Since we're hitting the museums a lot these days, thought I might get the annual individual membership costing $50 (LO is below 3 so she gets in for free most times) next time I'm there as they have a discount of 15% off membership subscriptions till 6 July. Dual membership is $80, family $120 and student $20. More details here.
