How do Chicago and Key West compare?
This pairing comes up almost exclusively as a winter-escape question — Chicago freezes by Thanksgiving and Key West stays at 75°F through April. American and United fly ORD to MIA in 3h10 for about $280 round-trip in winter, then a 4-hour drive south on the US-1 Overseas Highway across 42 bridges including the Seven Mile Bridge. Chicago is the Midwest flagship at $240 mid-range — Art Institute, deep-dish at Lou Malnati's or Pequod's, the Chicago River Architecture Cruise, Cloud Gate, Wrigley Field, blues bars, and a 26-mile Lakefront Trail you cannot use from December through March without crampons.
Key West is the southernmost-U.S. island town at $350 mid-range — small island, tight inventory, Hemingway's six-toed cats at the Whitehead Street house, Mallory Square's nightly sunset celebration, key lime pie at Kermit's or Blue Heaven, Duval Street bar crawls, snorkeling at the Dry Tortugas (a 2.5-hour catamaran ride to Garden Key), and the southernmost-point buoy 90 miles from Cuba. Best months invert cleanly: Chicago peaks May through October, Key West runs December through April when northerners flee winter. The Caribbean-style climate and pace are the entire point — no chain restaurants on Duval, no high-rises, walkable in a single morning.
These pair as a winter-escape arc — two Chicago nights for the Loop architecture and a deep-dish dinner before the connection through Miami, then a week of conch fritters and pastel Conch houses. As a year-round comparison, they are different trip modes entirely. Pro tip: book Key West lodging on the quieter Bahama Village or Old Town side west of Duval rather than directly on the bar strip — you get the architecture and walking access without the 2am Sloppy Joe's spillover noise that ruins Duval-facing rooms. Pick Chicago if you want a world-class Midwest metropolis with Art Institute depth, deep-dish, and lakefront energy. Pick Key West if you want a tropical winter escape with Hemingway, sunsets, and conch chowder.

🛡️ Safety
Chicago
Tourist areas of Chicago (Loop, River North, Magnificent Mile, Museum Campus, Lincoln Park, Wicker Park) are generally safe. Gun violence affects specific neighborhoods on the South and West sides that tourists have no reason to visit. Petty crime like phone theft occurs on the "L" and in crowded areas.
Key West
Key West is generally a safe small city for tourists. Old Town is well-policed and busy; the main risks are alcohol-related incidents (Duval Street late-night), aggressive scooter rentals on busy streets, sun exposure, and the seasonal hurricane risk. Petty theft from rental scooters and unattended beach belongings does occur. The island's relaxed, party-oriented culture means common sense is your best safety tool.
🌤️ Weather
Chicago
Chicago has a humid continental climate with extreme seasonal swings. Winters are brutally cold with wind chill off Lake Michigan, while summers are hot and humid. Spring and fall are glorious but brief. The lake creates its own microclimate — it can be 5-10 degrees cooler lakeside in summer.
Key West
Key West has a tropical savanna climate moderated by surrounding water — temperatures stay narrowly between 18°C (winter low) and 32°C (summer high) all year. There is a wet season (May–October, with afternoon thunderstorms and hurricane risk) and a dry season (November–April, which is also peak tourist season). Hurricane risk is real — Hurricane Irma in 2017 caused major damage to the Lower Keys.
🚇 Getting Around
Chicago
Chicago has an excellent public transit system run by the CTA (Chicago Transit Authority). The "L" (elevated/subway) train and bus network cover most of the city. A Ventra card works on all CTA and Pace buses. Driving downtown is stressful and parking is expensive — transit is the way to go.
Walkability: Downtown Chicago is very walkable and mostly flat. The Loop, Magnificent Mile, Museum Campus, and Riverwalk are easily covered on foot. Neighborhoods like Wicker Park, Lincoln Park, and Pilsen are pleasant to explore by foot. In winter, walking can be treacherous on icy sidewalks.
Key West
Key West Old Town is small (about 2 miles by 4 miles total island) and the historic centre is almost entirely walkable. Bicycles are the favourite local transport — flat terrain, dedicated bike lanes, and bike racks everywhere. The Duval Loop bus is free; Uber and Lyft operate but are more expensive than in Miami. Renting a car for the week is unnecessary unless you're visiting other Keys; parking in Old Town is scarce and expensive ($4-8/hour, $25/day in city lots).
Walkability: Old Town is one of the most walkable small-city centres in America — flat, compact, shaded by tropical canopy, and full of architectural detail. The full Duval Street walk takes 25 minutes end to end. Bicycles extend the comfortable range to the entire island.
