Late summer in Chicago is a perfect time in the city. The weather is great for exploring the city on foot, and there's plenty going on in the museums, theaters, and galleries downtown. It's still possible to sneak in a trip to Chicago before the end of the season, thanks to Starpicks. The Westin O'Hare is one of this week's participating Starpicks properties, with last-minute rates of at least 20% off regular rates for stays during the next two weekends. Conveniently located by O'Hare Airport, the Westin O'Hare has 525 guest rooms and suites, all of which feature the Heavenly Bed and Heavenly Bath, so you'll feel rested, refreshed, and ready to take on the town. The work of Jeff Koons is on display at the Museum of Contemporary Art Chicago through September 21, so it's a good time to admire his oversized metallic puppies and rabbits. The view from the Sears Tower is always hard to beat, as the tallest building in the western hemisphere offers panoramic vistas of Chicago, its surrounding suburbs, and Lake Michigan. And since you've got to spend some time out of doors when the weather is this nice, take in a free concert in Grant Park, a picturesque green space that's often referred to as Chicago's "front yard." It's a perfect spot to relax and dream up your next great Starpicks getaway.
