No. Photo ops are now sold per session as opposed to per guest, and may have multiple groups much like zones at airports for lining up. For example, you can opt to purchase a Mr. X photo op for his Friday session, his Saturday session, or his Sunday session. There will be a limited amount of photo ops per session and per group. This allows you to only arrive a 5 to 15 minutes before the start of your photo op.
Lining up more than 15 minutes prior to your photo op will result in security asking you to leave the area until it is time for your photo op. Once the line moves, it moves very quickly and often those that arrive closest to the session time, wait the least amount of time.
