I was originally told I could only pick our tickets up the day of the party, but decided later I'd feel better with them in hand. I called last week and asked that they be mailed to us. The CM said sure, no problem, and charged me $3 to mail them.
I figured that if most tickets are will-call, the line is going to be REALLY long to get them. I'd rather not do that if we don't have to.
