The Brooklyn Museum is worth the trip if you're staying in Manhattan on vacation. It's a short subway ride or walk the Brooklyn Bridge and catch the subway for 2 stops.
The Brooklyn Museum is not huge like the Metropolitan Museum or as fancy as MOMA but it has fabulous treasures in a walkable, manageable space that's spacious. You can breath in the Brooklyn Museum!
It's worth the trip to see Judy Chicago's exhibit. Once done, the rest of the museum has creative exhibits with well-written descriptions.
The Snack Bar has huge windows and the shop is wonderful with a variety of prices.
The subway stops 30 feet from the door. If you're getting tired of the hustle and crowds of Manhattan, take a relaxing afternoon in and around the Brooklyn Museum.
