But
I don't see how they could.
I think they just move the dessert party inside (if it's an outside event) and you miss the show. The dessert parties are usually sold out, so how could they accommodate Tuesdays party goers (example) on Wednesday? Even if they spread it out.... some Wednesday, Thurs, Fri.....not sure it can be done. And most people are only there about a week.
Honestly, I think they rarely cancel - it has to be almost hurricane-like. They will delay them, though. So, when the rain has slowed from torrential downpour to heavy, they hurry up and get their 10-15 minute show in.
