The urge to take yourself somewhere you've never been before will be strong, especially if you've got an equally spontaneous travel companion handy: and when don't you? It may not be a holiday, but you can always play hooky for a day and explore a little town a few miles away from you. Better yet, put your nose diligently to the grindstone for now, and spend the evening immersed in a pile of brochures and maps: with your cohort, of course.
