Arrived today for a 5 day stay. Went to Blue Lagoon straight from airport. Really, really enjoyed it - sooooo relaxing and sooooo hot in some areas!
Got to hotel about 5pm and asked whether lights had been out and was told that this week was a very bad week as whole of Iceland is covered in cloud - which you can see - and that even the tours searching for them have been cancelled :-(
Shame as our hotel room has a roof window (next to bed) which opens and then a small veranda opens with it so you can stand outside. If lights were out we could lay in bed and watch them. Never mind, we have a car and are looking forward to exploring.
Maybe someone could prove the weather wrong - please :-)
