Fiction.
The Arctic Circle is the line of latitude needed for a no-sunset summer solstice (or a no-sunrise winter solstice). The 900m altitude doesn't give you much more than 10mins extra at each end of the day.
http://en.wikipedia.org/wiki/Arctic_Circleeven the northern-most point of Shetland is a few 100 miles short. The Shetlanders describe "Simmer Dim" as the half-light all night through though.
Shortest day length up there is just under 4hrs, longest day just over 20hrs.
P.S. You can't see Iceland from Ben Hope either
