The Museum contains many amazing things. If you need help finding some unique highlights, pick up the free top twelve guide aimed at kids from one of the information desks. It lists places and pieces of art spread across the Museum that will guide you on a journey of exploration. The list includes Degas' Little Dancer, the medieval arms and armor, and the Chinese Garden. It is a great way to help kids get a taste of the variety of the collections, adults enjoy it too.
Both the Egyptian collection and the Impressionist collections are worth viewing multiple times. You can spend an hour and get a taste or spend the entire day and still have things left to see on another trip. The place will absorb as much time as you feel like giving it.
The food isn't bad so you can plan on getting lunch or a snack when you need a break from walking around the galleries.
Don't miss spending some time there when you visit New York City.
