I have some friends coming to visit the city end of May. They have two younger children. I have no kids so I was wondering if anyone could give me suggestions for fun family things for them to while in town? Thanks

Seeing a game at Wrigley Field. Lincoln Park Zoo, tours at the John Hancock Center and the Sears Tower.

Shedd Aquarium, Field Museum, the Adler Planetarium and Museum of Science & Industry.

Navy Pier has gotten to be major tourist attraction and has fine childrens museum.

If it's a nice day outside Navy Pier is a great way to kill a day with kids. They even have some rids (Ferris Wheel, etc..), tons of stuff to do for visitors. You can check out upcoming events at www.navypier.com

Also, check out citysearch.com...they have list of best family attractions:

Six Flags Great America is an amusement park where they could spend the day (and a lot of money). It's a bit of a drive north of the city in Gurnee.
