Why Joliet rather than Wilmington itself
Wilmington is a genuinely small town — roughly 5,500 residents — and the local lodging supply has not historically supported significant chain-hotel development. The handful of independent motels in Wilmington and the immediately surrounding area are mostly older properties of varying maintenance quality, and reviews skew inconsistent. For experienced Route 66 travelers willing to drive 15 miles for predictable lodging, Joliet is the closest practical alternative and the standard recommendation.
Joliet's lodging market is shaped by its position at the intersection of I-55 (the main Chicago-to-St. Louis interstate) and I-80 (the main coast-to-coast east-west corridor), which produces substantial business and leisure travel demand and supports a meaningful chain hotel footprint. The city has roughly two dozen chain hotels across the major brands (Marriott, Hilton, IHG, Choice, and Wyndham), with most concentrated along the I-55 corridor in the north and central parts of the city.
The Holiday Inn Express & Suites Joliet North specifically sits in the north-Joliet cluster along I-55, which is the side of the city closest to Wilmington and the Route 66 corridor. The drive from this hotel to the Gemini Giant is about 20 minutes (15 miles, mostly on I-55 with a brief exit onto local roads at Wilmington). Several other chain hotels in the same general area provide comparable alternatives if the Express is sold out or pricier than expected for a given date — the Hampton Inn Joliet I-55, the Fairfield Inn & Suites Joliet North, and the La Quinta Inn Joliet I-80 are the most commonly cross-referenced options.
