It's been a bumper season for this Canadian resort, which has already had more than its annual average of nine metres of snow with two months of the season left. Whistler has the most extensive terrain in North America with more than 200 runs, spanning 7,071 acres (La Plagne, by comparison, has less than 2,000 skiable acres). The average temperature is low until May, preserving all that lovely snow for post-Easter visitors. And you won't have much trouble getting a restaurant reservation - a tough proposition in peak season.
