Thank you all for your responses.  And yes, I had heard the same thing about their economy, but was wondering if it was really that much of a difference anymore? I’ll be sure to read the posted article.
April sounds like it might be a good time to go.  We typically do most of our European travel in mid March for some of the same reasons.  The weather seems to keep away a lot of the crowds and also keeps down prices.  Though I’m sure April in Reykjavik would be a little colder than March in London.
I’ll see if I can’t find the AA Guide here, or perhaps have a friend in Birmingham send me one along with my quarterly shipment of Coleman’s and Cadbury’s! 
Thanks again all- Kent, Mike and Marie - for your help.
