[Highland Park] passes to museums and zoo

Hi Neighbors, I have a family with 6 kids coming out to visit their grandparents next weekend. I was hoping to take the kids to see some Pgh sites like the zoo, Children's museum or Carnegie museum or Phipps, If anyone you have passes in your Entertainment books , or Kids Stuff Coupon books that you will not be using , I would love to have them so that we can afford to take them to see some of these things. Thanks! Erin
