Today we went to the Railroad Museum , LOTS of fun stuff to play with, indoors, and kids under 6 are free. Once they get done racing through the large railroad car exhibit, there is a small room with movies, and another room with Lego train tables, wooden train tables, Geotrax train tables.. .you name it. We only left due to hunger!

Hands on House - we have visited twice since spring - and it is a great way to spend some hours with kids - indoor (AC) and outdoor activities abound.

Also, I recently learned that with a zoo membership to Elmwood or Philly, you can get into Wilmington's Brandywine Zoo for FREE.
