I have tried the big-bus tours in other countries. However in Chicago, the tour is very personal with a tour guide in the cabin which I didnt experience before. The tour overall was good and takes 24 minutes between each stop, and it actually stops at all the key locations.
I am bad on names, i had the first tour guide who was informative then i went into a stop and tried another guide who was also fine and went into another stop. The last guide, Matty, I went with was so funny, informative and so close to the visitors; I literally didn't want to leave the bus because of him and his funny jokes. His Trump impersonations were so funny and accurate. Matty you made my day and I wish the trip was even longer
