I am planning to visit Greece this year and will go to Athens, maybe Hydra, Santorini, and Mykonos. I will have about a month in the country and I have never been to Corfu. I wonder if I should also visit Corfu this time around? Also, I am not sure Hydra is happening ... I will have time - Santorini/Mykonos will take up about a week of my time in Greece. What do you guys think?
