It may save you some money on your next family trip. We recently were in Portland, Oregon and our plans fell through for the day. So off to the Zoo we went. With our local zoo and aquarium membership we get benefits at over 150 zoos and aquariums which usually 50% off admission. This meant a savings of $12 and some cheap entertainment for the afternoon.
So be sure to see if your Zoo and or aquarium membership comes with benefits.
