Kids ages 3-10 go absolutely crazy for this place, and its Assembly Row entrance marked by a giant yellow LEGO giraffe. Not only can children build to their hearts’ content (and race model LEGO cars, and design towers and test their stability on the Earthquake Table) they can tumble, climb and slide in LEGO City Play Zone or catch a movie at the 4D Cinema. Tickets: $29.95 and up; discount when booked online. Open Su-Th 10 am-7 pm, F-Sa 10 am-8 pm. Last entry 2 hours before close.
