Fall in Icelandic Kroner makes now a good time to visit Reykjavik and Iceland.
About a year ago 1 of your British pounds would have bought you 125 Icelandic Kroner, today you will get more like 150 Icelandic Crowns to the pound. This is despite the fact that Sterling has fallen against many other currencies, notably the Euro. So while a trip to Spain is getting that much dearer, Iceland (never cheap, mind you) is now more affordable than for a long time.
Another nice thing is that Iceland is not in the EU so you can do real duty free shopping.
Check Iceland Express for cheap flights to Reykjavik. Iceland Express fly daily from London and other European cities.
