First of all, congrats! The best of love to you. Greece is becoming one of the world’s most sought-after wedding and/or honeymoon destinations. The best time of the year to plan your wedding or honeymoon in Greece would be fall or spring, when the weather is just right. A great quiet place would be Sikinos – read about it here or Folegandros, where I saw at least three weddings take place last year in my two-week stay. Read more here. Naxos would be a great idea too because it combines the best of Greece, plus the finest Greek food and its famous island music and dancing. If you're not keen on an island, getting married in Meteora and combining it with a road trip honeymoon across western Macedonia would be a fantastic experience. Get an idea of that here and here. You can also check out my post on weddings and honeymoons in Greece here.
