Organizer: North Michigan Avenue Association

What to expect: The trees along the Mag Mile will be illuminated, and plenty of sights and sounds will get you excited for the holiday season. The procession(beginning at 5:30 p.m.) will include more than 30 floats, marching bands and other performers, with Mickey Mouse serving as the grand marshal. ABC will be airing a national holiday special focused on the event, so expect to see 20/20 host Deborah Roberts there. Stop by Festival Lane at Pioneer Court (401 N. Michigan) during the day (11 a.m.-5 p.m.) for culinary demonstrations, musical performances (including The Plain White T's) and more.
