Illinois Route 66 ranges from expensive (Chicago) to very affordable (downstate). Smart planning means you can experience everything from deep-dish pizza to roadside diners without breaking the bank. Here's what to budget for your Illinois Mother Road trip.
1Budget Traveler — $60–90/day
Skip overnight in Chicago (or camp at Illinois Beach State Park, $20/night) and head straight downstate. Camp at state parks like Chain O'Lakes ($20–25/night) or find budget motels in Pontiac and Springfield ($45–65/night). Eat at Route 66 diners — Cozy Dog corn dogs are $3.50 each, Polk-a-Dot burgers run $6–10, and Lou Mitchell's breakfast is $10–15. Most roadside attractions are free: Gemini Giant, murals, and bridges.
2Mid-Range — $150–220/day
Stay at comfortable hotels in Springfield ($80–110/night) and a night in Chicago ($120–180/night). Budget $40–60/day for meals — deep-dish at Lou Malnati's ($18–25), steaks at the Cozy Dog's neighboring restaurants, and craft beer at local brewpubs. Paid attractions like Willis Tower Skydeck ($28), Art Institute of Chicago ($25), and the Abraham Lincoln Presidential Library ($15) fit this budget.
3Comfortable — $250–400/day
Stay at premium Chicago hotels ($200–300/night) and the Route 66 Hotel in Springfield ($90–120/night). Fine dining, rooftop bars, and all paid attractions without worrying about cost. Rent a classic car for a day ($150–250) to cruise the route in style. This budget lets you shop for Route 66 memorabilia at every stop.
4Money-Saving Tips
Chicago CityPASS saves $50+ on top attractions if you're visiting multiple museums. Downstate Illinois is significantly cheaper than Chicago — gas, food, and lodging can be half the price. Many of the best Route 66 stops are completely free: murals in Pontiac, Gemini Giant, Chain of Rocks Bridge, and every small-town photo op. Pack lunches for the I-55 corridor — fast food exits are sparse between Bloomington and Springfield.

Chicago is 60% of your Illinois budget — minimize nights there or stay in suburbs like Joliet to save $100+/night.
Cozy Dog Drive In corn dogs at $3.50 are the best value meal on Illinois Route 66.
Illinois toll roads (I-355, I-88) add $5–10 getting out of Chicago — have cash or an I-PASS transponder ready.
Free attractions outnumber paid ones 3-to-1 on the downstate route — don't feel pressured to buy tickets everywhere.
