Free to get in, an amazing aquarium, very cool exhibits, and you can see the space shuttle. By far our favorite museum. Even though it's free, we always donate money when we go in. Sometimes just a dollar per person, but more if we have it. Such a great deal for a family on a budget. And you can take the metro here, too! Gift shop is reasonable but the food is quite expensive!
