Here are 10 tips to make a trip to the Windy City easy to afford.
Chicago is on a roll. Millennium Park is wildly popular, and it just keeps getting better, along with the rest of the city.
These days, tourists have to compete with hordes of conventioneers and suburbanites fleeing back to the city. Prices, of course, have gone up.
Still, there's a lot to do for free. Here are 10 tips for making a trip affordable.

1. Go when business people and vacationers don't . Hotels are cheapest in Chicago on the weeks before Christmas, a fun time to be in town, and in the depths of winter.
I've also gotten very good deals on the long Memorial Day and Labor Day weekends and in late October for Halloween, which is a big deal in Chicago.
To get affordable hotel rates, avoid going when a big convention or event is in town. So before setting a date, check the Chicago convention calendar.
2. Get there cheap . You may still find $1 tickets on the Megabus if you book early enough, though $60 is more typical.
Amtrak also can be inexpensive if booked early.
Driving isn't cheaper once you pay for parking, which costs $40 and up per day.
3. Stay cheap . The Hostelling International family hostel in the South Loop, three blocks from the Art Institute at Congress and Wabash, is quite posh, with pancake happy hours, an Internet room and a carpeted great room with foosball, ping-pong, a pool table and a communal kitchen.
It has private as well as shared rooms, along with the Freehand Hotel/Hostel, in a former 1927 hotel in River North, and the Chicago Getaway Hostel near Lincoln Park, a renovated women's boardinghouse.

You could also stay at an Airbnb ; there are hundreds in Chicago. But they're not exactly cheap, partly because of a 23.4 percent tax on short-term vacation rentals.
In slow times (see No. 1), check Groupon Getaways or LivingSocial Escapes for deals.
Or exchange your home for one there. That saves not only the hotel rate, but the hotel tax of 17.4 percent.
4. See what's free. Start looking at the Chicago Cultural Center and, across the street, at Millennium Park. They both host lots of free performances, including the summer-long Grant Park Music Festival, with orchestra concerts at Jay Pritzker Pavilion.
On Michigan Avenue, across from the John Hancock Building, the beautiful, neo-Gothic Fourth Presbyterian Church offers free noontime concerts on Fridays year-round.
The Chicago Tribune lists what's new and coming up.
The services occasionally offer river cruises, opera concerts and walking and food tours as well.
In February, get tickets for $15 or $30 during Theatre Week.
If you buy and register the three-day card before you arrive, you can avoid the $5 fee for the reloadable card. If you buy it at the machine, you can register it later and get the $5 as a credit.
For bicycling, pick up a blue Divvy bike at one of the many stations around town. A daily pass is $15 and a single ride is $3.30.
7. Eat cheap . It's not hard. Along Michigan Avenue, look for Cosi, the Corner Bakery, Naf Naf Grill, Panda Express and Chipotle; you can eat well for $10-$15 at all of them.
At the foot of the John Hancock Tower, try L'Appetito, a great but unassuming Italian deli at the foot of the John Hancock Tower.
On the mezzanine level of Water Tower Place, eat at foodlife, a bazaar of made-to-order kiosks. But be careful; the food has so much eye appeal it's easy to run up the bill, recorded on a magnetic card.
And you can get a loaded Chicago hot dog and fries for less than $5.
8. Use coupons . If you plan to visit the big museums, buy a CityPass, good for nine days. It provides general and special-exhibit admissions to Shedd Aquarium, the Field Museum, Skydeck Chicago, the Museum of Science and Industry or 360 Chicago (former the John Hancock Observatory) and Adler Planetarium or the Art Institute.
Before you visit, subscribe to Groupon, LivingSocial and other deals for Chicago. Many offers are aimed at locals, but some are for theater tickets and tours, and there are lots of restaurant deals.
9. Go to museums on discount days . The big museums used to have one free day a week, but now they vary their schedules, except for the Art Institute of Chicago, which is free on Thursday evenings.
Mondays and Tuesdays in the off-season (which doesn't include December) are good bets, but sometimes museums schedule entire free weeks. There's a handy list of free days, mostly for Illinois residents, at Choose Chicago.
Because waits already are long at the Museum of Science and Industry, it may be best to avoid free day there.
And there are many other museums that are wonderful and also cheaper. Here's Choose Chicago's list of 20 Chicago Museums & Attractions for $10 or Less.
10. Have a Chicago Greeter show you around . Volunteer Greeters offer free tours of Chicago neighborhoods; reserve seven to 10 days in advance. There's also an Insta-Greeter service available at shorter notice.
