I come from Greece (SKG) and go there 3-4 times every year. Not going this summer, as I am far from keen on being around so many tourists, and the only sport I am really interested in is footy. Whenever I go to Athens I use a complimentary ensuite room at my granny's.
You could do a lot worse than avoiding 40C, mediocre hotel rooms that cost €300 a night and security measures that, as the Public Order minister proudly announced, "have been developed in collaboration with American and Israeli authorities and are using the US as a model".
