All the process with Klook ticket was easy and smooth. And I saved some dollars with it. I visited:
- Skydeck Chicago: great for the views. The glass floor is a must do
- Field Museum of Natural History: very interesting museum. The T-Rex is a highlight.
- Adler Planetarium: nice planetarium on the small size. Interesting exhibits.
- 360 Chicago Observation Deck: amazing views of the city. Recommended to go for sunset and stay until is dark.
Getting it from Klook saved me 10% compared to getting one from CityPass itself. Also got the mobile voucher within hours instead of the two day processing time. All the attractions have separate queues for CityPass holders, making this purchase very worth it.
Adler Planetarium and Shedd Aquarium can be done in one day.
Field Museum and Museum of Science and Industry needs one day each.
Skydeck Chicago can be done outside the museum hours.
