I don't normally like tempting fate but the costs of travel and accommodation at short notice specially for London on a Bank Holiday weekend are prohibitive for some people. I don't see it as being cocky, I just see it as a way of covering myself if we get there at a price I can afford and if we don't then the financial hit isn't too big. Reading the Mackem forum plenty of them have booked it in advance even though they admit their likelihood at the moment is small, I don't see them as deluded just not having loads of disposable income to book at short notice.
