This Navy Pier museum is three stories high and filled with engaging, educational exhibits including a dinosaur dig and a water play area (bring a change of clothes--kids will get wet). Kids also enjoy the big backyard and treehouse exhibits. Learn about fire safety in the Play it Safe exhibit where kids can practice safely exiting a smoky bedroom. Exhibits geared toward preschoolers and toddlers are gated. Older kids will love climbing on the museum's climbing schooner--three stories of ship's rigging from cargo hold to crow's nest. Through Jan. 10, build a snow fort, throw snowballs, dress up a snowman and ice skate - all inside - at Snow Much Fun. When you're ready for lunch, Navy Pier offers a food court and numerous restaurants. Plenty of indoor parking is available, but be prepared--Navy Pier parking is some of the most expensive in the city.
