Not at all. Some guests aren’t announced until very close to the event. Some guests have been invited but are unable to attend for a variety of reasons, including prior engagements like weddings, birthdays and other family events. Some guests have been invited but cannot attend because of scheduling issues or may not be able to commit to attend until very close to the event because their work schedules are in flux. We can’t demand their time, especially if the studio needs them for filming or promotional events at or around the time of the convention. Guests also may choose not to attend for other reasons including the option of time off for self care, and taking time out of the spotlight which we absolutely support.
We invite many more guests than are able to attend. If your favorite isn’t scheduled to attend this year they might make it next time!
