Me and OH are working on a tight budget, and found that Turkey and Greece are the cheapest places we have found which we'd want to go. OH has been to neither, and I have been to Greece. However, people have told me that because of the Euro, Greece is becoming more and more expensive to eat and as Turkey is (currently) still using the Lira, you get more for your buck. This isn't a bad thing, but as I've never been to Turkey I do have some concerns. I adore Greece, it's just a shame that we'll have to find more money if we want to avoid eating soup in our apartment everyday!
WWYD in our situation? Go with what you know, or venture into the unknown and try Turkey?
