I think a lot of the cancellation has to do with the location of the reception. It's a small town, 3.5 hours from Seattle with only a few hotels so everything books up way in advance. When my family used to take a vacation there they would book the same week for the following year upon check out. It's a beautiful area and the views from the ceremony location are the best, but after Labor Day the weather turns and anything past early October is just gray and depressing so there may have not been anything available that, #1 their guests could find lodging, #2 the weather would have cooperated. Finally, with fire season kicking up in August and 90+ degree days, it's not very pleasant either.
