Travel
- Out of town guests fly into ORD and take an uber or city taxi into the city (thirty minutes to one hour depending on traffic). -- - Driving downtown for international drivers isn't suggested- there is a lot of traffic and parking is a nightmare. The city is very walkable and cabs/ubers are on every corner. USD or Credit Cards work in taxis.
If you are renting a car, I would use "spot hero" for parking (spothero.com). If you put in the address they give you discounted rates at garages near the hotel. Parking at hotels downtown is super expensive ($60+/night)
