Our plans are coming together for our train trip to Chicago. We will be arriving by Amtrak. We have just been offered a stay in a friend's condo (Aqua) near Milleneum Park. (Wow - what a gift!) I don't know if the El would take us near there. The children would get a kick out of riding it. We arrive on a Thursday and I noticed that the Children's Museum is free on Thursday evenings. I wonder if the crowds will make it impossible to enjoy. Friday we will spend time at the Shedd's Aquarium and then maybe take a boat ride. I read that there is a Lego store - I'm sure they would enjoy that. I don't think we need to do a zoo because St. Louis has a top-notch zoo. We will plan to go to either the Sears Tower or John Hancock building for the view. Any other ideas - places to eat, etc. The children are 6 and 8.
