Our guild contracted for the Quilt Bus in March. We had ads in the papers and were preparing for their visit. The day before they were to arrive, it was learned that they had had mechanical problems in New England and would not be able to make it. They offered to send a van, but no classes or lectures. Needless to say, many were disappointed.
Inasmuchas the guild had not contracted for a "van" the event was cancelled. The local radio stations tried to alert prospective visitors, a notice was listed in the papers, but still 50 or so folks came to the site. And since the guild wanted the "bus" and they offered to send a "van", we were not refunded our deposit. The guild felt that there was a breach of contract.
We did not doubt that they had mechanical problems, but the guild will not reschedule them for obvious reasons.
