taxi
Estimated costCost TBA
Best forChicago O'Hare International (ORD) to the venue
Allow 30-50 minutes off-peak and longer in the morning or evening rush. Taxi ranks are outside each terminal; rideshare pickup zones are signposted separately.
rideshare
Estimated costCost TBA
Best forChicago Midway International (MDW) to the venue
Midway is closer to the Loop than O'Hare, so fares are lower outside surge periods. Follow airport signs to the designated rideshare pickup area and check the app for the current estimate.
metro
Estimated costCost TBA
Best forCTA 'L' and bus trips within downtown Chicago
Use Ventra or contactless payment for trains and buses. The Loop is compact and walkable, but the 'L' is faster for lakefront and Near North venues; confirm pass options and current fares.
parking
Estimated costCost TBA
Best forDowntown Chicago garage parking near the venue district
Downtown garages charge by the hour or day and hotel valet rates are often higher. Airport-cluster hotels in the capture advertise on-site parking; confirm the rate when booking rather than assuming it is free.
shuttle
Estimated costOften complimentary; confirm with the hotel
Best forAirport hotel shuttle to O'Hare or Midway terminals
Several airport-area properties run scheduled shuttles to ORD or MDW. Ask for the timetable at check-in and allow extra time for the loop around terminals.
Weather
Late April in Chicago is a transition period: mild afternoons, cool mornings and evenings, and fast-moving spring showers. Lakefront wind can make temperatures feel several degrees lower near the venue district. Check the National Weather Service forecast in the final 72 hours and keep a rain layer in your day bag.
Plan for the climate
Check temperatures and pack accordingly
Venue connectivity
US mobile networks (Verizon, AT&T, T-Mobile) cover downtown Chicago well, and an eSIM bought before departure is usually cheaper than roaming. Hotel and venue Wi-Fi is common, but check whether conference Wi-Fi is included with registration. Power is 120 V at 60 Hz with Type A/B plugs, so UK and European devices need a plug adapter and, for some equipment, a voltage converter.
Ride-hailing
Taxis
Public transit
Car rentals
Cultural notes
Useful information to help you have a smooth and respectful visit.
Business dress
Chicago academic meetings lean business casual; a blazer is useful for evening receptions at downtown hotels, while conference days are usually smart casual.
Tipping
Plan for 18-20 percent tipping at restaurants and bars, and a small cash tip for hotel housekeeping and bell staff. Taxi and rideshare tipping is expected in the app.
Getting around
The CTA 'L' is the fastest way between the Loop and the lakefront; rideshare pickup zones at both airports are clearly marked. Downtown blocks are walkable but wind between tall buildings can be strong.
Reservations
Downtown restaurants fill quickly on Friday and Saturday nights and during large conventions. Book popular tables a week or more ahead, or eat slightly earlier than the local rush.

Visitor & Exhibitor Essentials
Everything needed to arrive prepared, navigate the event, and make the visit productive.
Flights
Destination: ORD
For a 30 April 2027 departure, book six to ten weeks ahead and set a price tracker rather than waiting for a last-minute fare. ORD is the main international gateway with nonstop links from New York JFK, London LHR and Tokyo NRT in the Google Flights capture, while MDW is convenient for domestic connections. Late April is not a major Chicago convention peak, but fares rise around spring break and graduation weekends, so compare ORD and MDW before committing.
Transport
Get to the venue and around the city with these options.
Airport → venue: Primary gateways: Chicago O'Hare International (ORD): 30-50 min off-peak; 60-75 min in rush hour; Chicago Midway International (MDW): 20-35 min off-peak; 45-60 min in rush hour. Allow road or rail time to ; on-site parking is usually available at major exhibition venues.
Hotel → venue: Precinct hotels near : Downtown Chicago (The Mart): Holiday Inn Chicago Dwtn - the Mart by IHG; Midway Airport: Holiday Inn Express & Suites Chicago-Midway Airport by IHG; O'Hare Airport: Holiday Inn Express & Suites Chicago O'Hare Airport by IHG.
Ride-hail: Uber and Lyft operate across Chicago, including designated pickup zones at O'Hare and Midway. Fares rise during commute hours and convention peaks, so compare the app estimate with the CTA for airport runs. Confirm the pickup zone on arrival signage rather than hailing from the terminal curb.
Public transit: The CTA 'L' connects both airports to central Chicago: the Blue Line serves O'Hare and runs 24 hours, and the Orange Line serves Midway. Standard rail and bus rides are approximately USD 2.50, with a higher O'Hare station fare; pay with Ventra or a contactless bank card. Allow extra time during morning and evening peaks and confirm current service notices on transitchicago.com.
Parking: Downtown Chicago garages typically charge about USD 40-75 per day, and hotel valet rates are often higher, so confirm before booking. Airport-cluster hotels near Midway and O'Hare advertise on-site parking, which can be cheaper for a driving trip. Do not assume hotel parking is free unless the rate sheet says so.
Weather
Plan and pack for the event climate.
Month: Late April 2027
Temperature: Expect daytime highs of roughly 15-21 C (59-70 F) and overnight lows of 6-11 C (43-52 F). Lakefront wind can make the venue district feel cooler, especially in the early morning and evening.
Seasonality: Spring is Chicago's showery season, with fast-moving fronts and gusty lakefront winds. Rain is usually intermittent rather than all-day, so a compact umbrella and a light waterproof layer are more useful than heavy rain gear.
Packing: Pack layers for cool mornings and warmer afternoons, a packable rain shell, comfortable walking shoes for the Loop and lakefront, and a light scarf or windproof jacket for evening walks near the water. Bring a universal power adapter if you are travelling from outside the United States.

FAQs & glossary
Answers
Frequently asked
What is the IARS annual meeting?
It is the annual scientific meeting of the International Anesthesia Research Society, a US-based professional society for anesthesia research and education. The 2027 edition is scheduled for 30 April-2 May 2027 in Chicago, Illinois.
Where exactly in Chicago will the 2027 IARS meeting be held?
The listing confirms Chicago and the 30 April-2 May 2027 dates. A verified venue address and hotel block were not exposed in the source material for this listing, so check the venue and accommodation pages on iars.org before booking non-refundable travel.
Who attends the IARS meeting?
The audience is weighted toward academic anesthesiologists, physician-scientists, anesthesiology residents and fellows, critical care and perioperative physicians, pain specialists and research coordinators. Industry medical affairs and R&D staff also attend to follow the science.
Is the meeting aimed at researchers or practising clinicians?
Both. The programme is anchored in research, but the point of presenting perioperative, airway, pharmacology and safety data is to change clinical practice, so practising anesthesiologists use the meeting to hear findings before they reach routine teaching.
How do I register and what does it cost?
Registration is handled through iars.org. Member, non-member, trainee and one-day categories are typically published on the registration page, but this listing does not carry a verified 2027 fee schedule - confirm current rates and deadlines directly on the site.
Can I submit an abstract to the 2027 meeting?
Abstract submission is managed by IARS through its official site. Check iars.org for the current call for abstracts, word limits, submission categories and the deadline for the 2027 edition, since these dates are set by the society each cycle.
Will CME credit be available?
CME accreditation and credit hours are determined by the society and its accreditor. Confirm the accredited sessions, credit type and evaluation process on iars.org before you book travel for credit purposes.
How do I get from O'Hare or Midway to the meeting?
From O'Hare, the CTA Blue Line runs directly to the Loop in about 45 minutes; from Midway, the Orange Line takes about 25-30 minutes. Taxis and ride-hailing are faster door to door outside rush hour. Confirm current CTA fares and service notices before travel.
What will the weather be like in Chicago in late April?
Expect changeable spring conditions: daytime highs typically 15-21 C (59-70 F), overnight lows 6-11 C (43-52 F), and frequent passing showers with lakefront wind. Pack layers and a compact rain shell.
Can international attendees get a visa invitation letter?
Visa support is handled by the organiser, not by this listing. Check the registration or international-attendee pages on iars.org for any invitation-letter request process, and apply for ESTA or a B-1/B-2 visa well before departure.
