Sorry if anybody has answered my query but I can't find the thread! We can't go in August because it's too expensive (4 adults and 1 child; if only you could turn back time) and we are finding it a bit tricky as eldest DD has exams. However is it better to book with VIrgin asap or doesn't it matter if you leave it a bit? Which time of year to coincide with school holidays is cheapest (even if only part of the trip is in the holidays)?
