Are you going to the closing ? I've been humming and hawing but might get some flights as they are bound to be something stupid by the time the rest of the world recovers from Christmas. They'd better not muck about with the date if I do !!!!!!!!
By Summer, September flights from BHX or BRS are above £250-£300 if you want to arrive any time there's a car hire desk open - cost me over £250 one way to get home early even to a London airport last October and
The bulk of my Ibiza budget nowadays is aimed at boats, car, watersports etc.. the costs of which very easily run into the thousands not the hundreds overall. Paying an arm and a leg for flights and hotels just makes other places much better value overall because Ibiza ain't cheap for water-based activities either unless you work very hard at getting things heavily discounted.
