My daughter and I just returned from Chicago yesterday. I suggest you get a Go Chicago Pass. You can buy them for one day only. It gives you an all access pass to Shedd Aquarium, Adler Planetarium, Field Museum (boring for a 3 y/o!), Sears tower, etc. The drawback is that you have to do these things before 5:30 pm. Public transportation is the way to go in the city...traffic is VERY thick and parking prices are exhobitant. And Giordano's is THE place to eat deep dish pizza. Enjoy

Great information.Thanks all of you. special thanks for pizza..I will definitely checkit out.
So, you suggest Hancock rather than sears towers?? Is it becoz of less crowd?

Repeatedly that advice is given bond007, not just because of crowd or lines- but because of location. Sears Tower is in the West Loop area and a short ride or long walk from the other more Northern and Eastern locations.

Actually, I don't think the Hancock is a substitution- but I'm in the minority. Tallest is the tallest. And from Sears I think you can see more of the city itself and not just the lake and skyscrapper areas. That's on a clear day. Today you would see next to nothing as it's real foggy.

And also actually, I think the best "view" IMHO, is from Swissotel's gym/work out room/swim pool area. It's on a peak of landfill in the lake and from there you can see the entire curve of the lakefront all the way South to Hyde Park, if it's clear.

Since you are not going shopping I might stick with the Sear Tower versus the Hancock since the Sears Tower is so close to your train station. Then take the water taxi, etc. per placeu2's great itinerary.

Have a great trip!

All of you- thanks for advice.I think, I am now cofident @ my successful trip, with all your advice.(I was a bit in-doubt,as being 1st trip.
One Q:for sears tower/shedd,should I buy online ticket or get one on-the-spot?
