This is a ranking of conference hotels in Illinois by meeting and event capability, drawing from the hotels available to book through Engine.

The page serves event planners and travel managers booking rooms and event space across Illinois, as well as attendees booking their own stay.

Illinois draws corporate meetings, industry conventions, and large events year-round, from Chicago's lakefront to convention-ready suburbs across the state. The hotels on this list serve organizations of every size and industry, whether you're coordinating a sales summit, an annual conference, or a multi-day training.

Same order as the list above: ranked by a hotel's total event space across all its meeting rooms. The largest single room is shown here, so that column can run out of order. Space figures come from each hotel's meeting-space records. A dash means the hotel's data doesn't list that detail, not that it's unavailable.

Frequently asked questions

How far in advance should I book hotel rooms for a conference in Illinois?

For large conferences, book guest rooms at least three to six months ahead, especially if your event falls during peak travel periods or overlaps with other meetings in the city. Properties like the Marriott Marquis Chicago and the Renaissance Schaumburg Convention Center Hotel can fill early when demand is high. Booking early also gives you more options for meeting space and room-block rates.

How do I book a block of guest rooms for conference attendees?

If you need nine or more rooms, Engine Groups handles the room-block booking for you. For eight rooms or fewer, you can book self-serve directly through Engine. Either way, you get pre-negotiated rates and no membership fee.

Can Engine help with both the guest rooms and the meeting space for my event?

Yes. For the guest-room block, Engine Groups handles bookings of nine or more rooms, and you can book eight or fewer self-serve. For the meeting or event space itself, you can find and request a venue through Engine Spaces, which gives you access to thousands of options across the country. That means one platform to help with both sides of your conference.

How does billing work when I book a large room block for a corporate event?

Engine offers consolidated invoicing, so you get one clear bill instead of managing individual charges. You also have multiple payment options and no membership fee. That makes it easier to reconcile expenses and stay on budget for a multi-room booking.

What should I compare when choosing a conference hotel across different Illinois cities?

Compare the size of the largest event space, the total number of meeting rooms, and the guest-room count to make sure the property can accommodate your group. For example, the Marriott Marquis Chicago offers a largest event space of about 100,000 square feet and 1205 guest rooms, while the Renaissance Schaumburg Convention Center Hotel has a largest space of about 97,000 square feet and 500 rooms. Also consider location relative to the airport serving each city and what's nearby for attendees between sessions.
