There is no additional fee for the Cyclorama, but you must choose an admission time (it's a separate line item on the online ticket purchase screen, below where you choose the number of adult, child, etc., tickets).
There is not an additional fee for the Cyclorama. It is included with standard admission; however there are limited spaces per showing. So one should either book a time online in advance, or stop by admissions on the way in to obtain a ticket for a specific showing time.
