CityPass is a must
CityPass is a must! We got the one for our trip to Chicago and it was a time and money saver. I really appreciate how you can easily book ahead, skip lines, etc. For example, when we went to the Art Insititute, the lines were out to the street. We walked right in. Easy peasy. The app is super helpful and easy to use. We will definitely look into CityPass on our next vacation.
