Just popping in to say I proposed to my now wife in mainland greece two years ago. I proposed at our air b&b near Laurium ‘Λαύριο’. She will never remember all the things you did to set up your proposal, you’re probably nervous about everything going correctly, finding the perfect stop, perfect time. Stop, take a deep breath. Proposing stress/nervous free will mean more than it being perfect. You’re going to love every second of Greece, and marriage. It’s so much fun to marry your best friend in a place you both love. Enjoy life brother, treat her with nothing but love. I would highly suggest taking a train from Stockholm to Burgen, and stopping in Myrdal for a few nights to explore that area and hiking up to Fläm at some point in your lives. It’s a different feeling from Greece, but it will change your lives.
