Greece remains one of the world's oldest and premier destinations for travelers and a visit there should be an occasion for sheer enjoyment -- even exultation. There is no denying, however, that as this guidebook goes to press, the news and images coming out of Greece have been unsettling, and remain unsettled. Greece's finances, economy, government, and society all appear to be in turmoil.

Most museums and archaeological sites have remained open, but often with reduced hours (and even days of closure). If Greece's economic difficulties continue, it is possible that some stores, restaurants and hotels may change the times that they are open, or even close. Not to worry: there are more than enough other hotels, restaurants and shops that we recommend to help you have a great trip. Assuming that Greeks do adopt the necessary reforms by the time this guide is in your hands, we believe that most visitors will be able to go about their travels without being unduly inconvenienced.

Planning ahead has always been advisable for any trip, but with the economic crisis that Greece has been experiencing since 2009, a new layer of warnings comes into play: Many prices of hotels in particular and hours of admission to museums and archaeological sites have been in more than usual flux. Although we have tried to account for these changes, we are not oracles (so to speak).

Still, as with any destination, the ease, comfort, and pleasure of your time in Greece will be greatly improved with some planning ahead. This guide provides a variety of planning tools, including information on how to get there; tips on accommodations; and quick, on-the-ground resources. One constant we cannot stress enough: If you are planning to visit Greece during the peak season -- from July through August, and even from mid-May to mid-September -- you are advised to make reservations for airline fights, hotels, and even major cultural events well in advance.

Packing -- As most visitors to Greece tend to be there between the first of May and the end of September, light jackets and sweaters should suffice for any overcast days or cool evenings -- unless, of course, you are planning to spend time in the mountains. Except for the really high-class hotels and resorts, casual dress is accepted in almost all restaurants and facilities. But Greeks remain uncomfortable with beachwear or too-casual garb in villages and cities. And females are expected -- indeed, often required -- to cover their arms and upper legs before entering monasteries and churches. Some priests and monks are stricter than others and may flatly bar men as well as women if they feel that the men are not dressed suitably.
