I am going on a solo trip on 21st August for 2 weeks, I am flying into Athens. I have a friends wedding in Santorini where I will stay for 3 nights on 27th. I am hoping to spent time in two other islands before and after the wedding. I am looking for some ideas of less touristy islands, where I can walk/get buses to explore, with good food, beaches, and where I can meet friendly people and learn more about greek culture. All suggestions welcome- have very little time left to start booking ferries/accommodation.
