Keep your NY to Seattle flight. Any flights that crosses the border will be expensive. Instead, from Seatac, take the greyhound to Vancouver Airport. Then from Vancouver Airport, take the Pacific Coach Lines to Vancouver train terminal on Main Street. Then, hop on the Whistler train and it'll take you up to Whistler. This way, you don't have to worry about driving, road conditions, directions, and you can enjoy the scenic train ride up to Whistler.
