Yes, the first week in January will be better. The second week in January will be a little better still. Basically, the week between Christmas and New Year's is the busiest week of the year at these resorts. In fact, there tends to be a correlation between the number of children off from school and the occupancy at the resorts. I can only speak for the U.S., but once you get past New Year's Day most children will begin to return to school, easing the crowds at the resorts. January can still be a popular time to vacation away from winter weather, but it will not be as bad as the week of Christmas and New Year's.
