Can you go up as a group, and how much do they charge per person?

If you can upload in a group, sorry for the memory I don't remember the price

They charge US$23.00 per person at the ticket booth or US$99.00 (per person) for the CityPass, which includes admissions to other attractions in Chicago.

When I was there between Christmas and Thanksgiving, no charge, but you could buy pics, the kids with Santa, souvenirs, etc..

$ 25 per adult

$ 24 per adult
