Where is the best place to park

what hall are you going to? if north or east hall...lot C. if west hall...lot A. depending on where your coming from, i.e. the Stevenson or Dan Ryan, make your way Martin Luther King drive. then follow the signs

Follow directions based on your travel direction and the exhibition building you are planning to attend - North, South, or East. Also look into alternate transportation - taxi - Uber - Metra Electric - CTA bus #3

I always park north on the street free parking

There are lots all around just follow the signs depending on your route. Street parking North of Mccormick if your lucky. Take an Uber.

Metro is best to take n then taxi

Parking is an tricky thing
