I tend to agree with what Mr. Batters had to say. Coming from the west, I do the gruelling flight on a regular basis.
If we could separate and possibly do four days in the west, hit Vancouver, Calgary, Fort McMurray, and Whistler in four days and then do it on a weekend, so we do it Tuesday to Friday and then fly back on Friday, then people can choose if they want to stay over on Saturday or Sunday—it's their own time.
