Just a heads up, the person who bought the tickets should have received an email this afternoon with some additional information about Block Con!
If you have VIP, the meet and greet photo ops are spread out over 2 days - group A on Friday night and group B on Saturday. Your group assignment came in the email that was sent out today.
Also, they also divided the check in times into 2 groups. Group 1 is to check in at the Rosemont Theater between 1pm and 4pm and group 2 is from 4pm to 7pm. If you can't make your assigned time, you can still check in later to pick up your credentials. If you are available on Thursday night, you can also check in early from 6pm-10pm at the Hyatt Regency Hotel.
They also included a more detailed schedule, which is pictured below:
Here are some additional screenshots from the email:
