Spanish holidays have never been more popular. So teachers, stuck with rigid holiday timetables, have to be even more clever than usual when choosing where and when to go. For a really relaxing time, avoid the summer costas and pick a half-term break in the less well-known north, often known as "green Spain". Travellers' Way, a company with properties across the rugged north, in Galicia, Asturias and Cantabria, is offering TES readers 10 per cent off accommodation in northern Spain during all three half-terms this year.
