Think of photo ops as a voyage to an exotic destination - you can only board one plane at one time and wait for it to land before boarding another.
Even as VIP you cannot be in two places at the same time and we still require you to arrive at the photo op on time. Some talent may be late or have long lines while others have short lines. Once the last person in line has had their photo op taken, the talent leaves. If you choose to purchase photo ops that are at the same time or close together, please be aware that we will not give refunds for missed photo ops and you do so at your own risk.
At a large convention we recommend at least 20 minutes between photo ops.
