I'm too lazy to break down that site like ChrisC did. In terms of volume it's fairly simple. The Brits and French ski in France. The Germans ski in the other alpine countries. The Dutch ski in all of them. Since the notorious British February holiday week coincides with one of the French weeks, that week in France is the worst scenario outside of Christmas Week. The latter usually sucks for the same reasons as in North America: large crowds on incomplete terrain. Mardi Gras week has the highest proportion of Germans on holiday aside from Christmas.
British and French coincide over Easter Week too, but the volume is not at the level of February. James with his strict standards might not like it, but Liz and I have been there during parts of 3 of them and found them manageable.
