Flight
You can fly in to either Chicago O'Hare Airport or Chicago Midway Airport (hint, if you're flying Southwest you'll be flying in to Midway!) There are car rentals and Ubers at both airports, and both are roughly the same distance from the hotel and wedding venue.
Rental Car
There's no two ways around it - this is a suburbs wedding and all the good stuff to do is in Chicago! We've snagged blocks of hotel rooms (see below) at hotels in Naperville, and the wedding is in Aurora. For this reason, we highly recommend getting a rental car for the weekend! You can pick up and drop off a rental car at either airport. If you don't want to take a rental car, you can definitely find Ubers (yes, even in the suburbs) and can easily take the train to downtown Chicago from most suburbs (just Google the Chicago Metra and find your nearest line!)
Hotel
We have reserved a block of rooms for out-of-town guests at the Embassy Suites in Naperville. The price includes free breakfast and cocktail hour each day of stay. Guests wishing to take advantage of this block should call the hotel directly.
Discount Code - WHW
Hotel
We highly recommend going for the Embassy Suites rate first (nicer hotel, better price, breakfast/cocktails included!) but if the rooms book up, we've also grabbed a discounted rate at the Marriott nearby!
House Or Rental
You will find no shortage of great Airbnb rentals in nearby towns a quick drive from the wedding venue. We do not recommend staying in Aurora, but we definitely recommend staying in Geneva, St. Charles, Batavia, Naperville, and Wheaton. Pay special attention to places that say "guest house" or "coach house" - those are super common in the area, and you'll get a great rate and be guaranteed privacy!
