If you’re not a parent, and therefore have no constraints regarding when you can take your holiday, do not, I repeat DO NOT travel in February. As dramatic as this may sound, I can assure you that your first ski experience will be far better if you visit any other month of the season. February is the month in which schools from all over Europe close for one week each and so family holiday season begins.
It is the busiest month for ski schools, so booking a lesson will be harder and potentially more expensive. Lift queues will be hellish, even with an instructor guiding you through them, and the slopes will be packed with people, all of whom are hazards when you are learning to ski. January is usually the best time to visit Avoriaz, as the snow is almost guaranteed to be good, the slopes are quieter and the flights are cheaper.
