I've done both snailmail and willcall, and had satisfactory results with both. The crowd at the booth was minimal (and fun to look at, indeed!) so that was no problemo, even on a monday afternoon; My secure-delivery ticket came exactly one week after ordering. Although to have a real ticket does risk losing or forgetting it sometime during that most-of-the-rest-of-a-year, I just like having it around as an antidote to snowy Michigan winter days.....The tickets look cool this year, too.
