Hello, Here's the itinerary: https://www.tripoto.com/trip/honeymoon-5ab9f4c8ef35b
It's beautiful place with breathtaking views. There are variety of shops and restaurants which can lure you. Cost for one person is around 90k(4 star hotels and fights including). We visited Athens, Santorini and Mykonos... but I would suggest you should also visit Skiathos, Milos and Zakynthos along with it... if you have ample time or choose among them. You can easily get ferry's in the morning to take you to these islands. You can find that info easily.
Hope you enjoy your trip as much as we did.
