Planning a trip to Canada last week of June next year with 3 teenagers from the hot tropics in Australia. Will there still be any snow to see? Kids have never seen snow before. Also, will the chair lifts still be operating? Any tips or suggestions much appreciated. Thinking of spending 3 nights in Whistler then driving to Banff for 3 or 4 nights...or should we just spend all our time around Whistler area, maybe even Victoria?
