For me it has to be further than anywhere you would drive to for a day trip. We will drive up to two hours for a day at the seaside - say, to Scarborough from here but we prefer the coast further North up to Whitby and there and back in a day is really too far so it has to be a short break. As for the countryside, we can fall out of bed into the Peak District, but for the Yorkshire Dales, it has to be at least a weekend. A proper holiday, though, is anywhere it takes you most of the day to get to; Scotland, West Wales, the West Country.
