We've been going to a friends villa in Spain with our children for last six years during peak time August. Have always used Easyjet on Gatwick to Alicante route. I've always agreed with villa owner holiday dates available way in advance as it Pays to set up a Flight Alert via website and book as soon as Easyjet tickets are realised end November. For a family of four - tickets can only be £80 each one way on immediate release (you need to book within minutes of release) rather than £180 each one way later on. We've always arranged to have three hold bags (between four of us - at extra cost) and our car hire with Europa car via the same Easyjet booking. With two children whilst we've never paid extra for seats - with early online check in have always sat together. Actual trip on plane is straightforward and simple with self service check in at Gatwick and drinks/snacks to have on plane. Have never had a problem - reliable way of getting from A to B.
