I can tell you that in what we call the “high season”, the summer months between May and October, one day's revenue can equal a week's revenue in February. I think that gives you a sense of how a lot of businesses really rely on that summer season. Of course, there are businesses that are solely winter season, but in a number of sectors—the business event sector, for example—they really rely on the shoulder seasons.
At this point, I will tell you that the split between those who need to have year-round revenues and those who don't is about 60:40.
