I've always picked up my tickets an hour or two before the show. You should receive an email with instructions from the Paramount.
Hi Claire! You may pick up your tickets during our box office hours W - F 10 AM - 2 PM or the night of the performance at our Will Call under your last name.
Will Call
At the door the night of the show
I always pick up my ticket right before the show at will call
