My tip is to travel to La Grave in France. Stay at Skiers lodge with Pelle and his crew, and you will be guaranteed powder. They have minibuses to transport you to neighbouring resorts if the conditions are below par i La Grave. I've been to Chamonix, St Anton and Alagna as well, all great places, but my best powder experiences have been in La Grave. Check out www.skierslodge.com
