Rolling cancellations, month-by-month, I suppose. Quite a few firms are doing this. The variation is how far ahead they're looking - 4, 6, 8 or 12 weeks. I've just had an email saying that a music festival planned for early August has been cancelled. I guess the organisers were about to pay a large bill (concert hall hire?) so pulled the plug while they could still cover their liabilities. Other organisations won't want to lose the chance of some (any!) income... Expect announcements about WCRC May excursions around 20th April?
