I've stopped for a third night in Symi because there was another beach that I wanted to walk to. My legs were complaining so much that I had to have a little sleep when I got back.
Good news is that the temperature has dropped quite considerably in the last few hours, so now its a very pleasant evening. I'm off for something to eat, probably a pizza because that's what I had last night, and it was excellent.
Tomorrow it's Kos hope I can find somewhere to stay.
