People tend to check in during these times:
Really great museums for children with the crooked house and the electricity ball and much more
This was my favourite museum as a kid, and still is, largely due to all the interactive elements.
Plan lots of time. Tons for the kids to do
The summer camp programs here are great.
A voir!!!!! WOW!!!
March is Engineering Month. Lots of special activities going on.
Do not eat at their cafe--ridiculously overpriced!
Bring the kids, camera and a homemade lunch !! Great picnic place.. :)
Avoid the cafeteria, it is ridiculously expensive and noisy.
It's not immediately apparent, but there is additional parking at the rear.
Go on a day where the children are at a low level to enjoy the place to it's fullness.
