Those who take week-long ski holidays, how do you handle the fatigue?

I find it hard enough to ski three days in a row without a day in between for recovery, let alone seven days in a row. I always wonder how people manage a week-long ski holiday, as I've heard many people take yearly.

Do you just not ski all of the days, or just ski a few hours a day, or do you just ski through the pain and soreness and accept that time will be wasted due to poor performance? Especially those for whom the ski holiday is their main skiing for the year and thus aren't in amazing shape.
