I am pleased with the reviews presented. They are overwhelmingly favorable, and I have little to add. In any country you visit be polite, appreciative and patient. Learn a dozen useful words : a respectful salutation, please, thank you, yes, no, where is ... ? How much is it ? the subway, the toilet, a physician, the bill ( please), etc. Read a guidebook you like ahead of time, plan what you're going to do and take the guidebook and a map with you. SMILE genuinely, and you'll have a great time ! I liked Athens.
