If you are traveling alone...just remember as in all big cities or little cities to be careful. My hubby is from that area and he recommends staying in downtown so hope it works for you to stay in downtown. The last time we were there it was over the 4th of July and won't do that again...it was too crazy at the Pier.
We had a great time at the musuem. Even if you do not go to the museums take a drive to them. It is so pretty!!
The Navy Pier was fun the other couple of times we were there. We did the drive by Sears Tower, but did not go in.
You will have fun just be careful. The first time I went ...I asked my hubby why do the police have police dogs with them?? This was in the parking garage at the Navy Pier. That was a first for me, and seeing the transit system the "L" I had not really been to another big city other than Dallas was cool to see the difference yet some of the same.
Have fun!!
