"Amazing Chicago's Funhouse Maze at Navy Pier-20 minutes (or so) of fun. They loved it more than anything we did. Before you enter the maze, you wait in an elevator, which appears to plummet.  The doors opened and inside the maze, the kids bounced off each other like loose marbles; inside the maze tunnel, which seems to roll and rock beneath a field of stars, they sat on the floor. They went through five times, and stumbled out like zombies, arms forward.”
