I think it was a last-minute decision, cause they were sending me schedules just a few days before. I'm sure they were really trying to make it work and I know they invested a lot of effort into it. (I waited until they posted the cancellation on their site before posting it here, though it was several days before that that they told their vendors.) Maybe a single event would be best in the future (like they had done in the past), so everyone plans to attend at the same time.
