Answers about Greece
A good suggestion would be to visit with a licenced professional tour guide of greece the following sites.Athens(Acropolis,Agora,New acropolis museum,Cape sounion),Argolis(mycene,Epidaurus,Nafplion),Olympia,Delphi,meteora.there is yet more to see in a tailor made way
My suggestions for 10 days in Greece ( a week is not enough!)
Athens: A must is the New Musuem of the Acropolis, if possible with a good guide
Meteora, Navplio ( and surroundings), Mani. Islands: Hydra, Small Cyclades, Santorini
Since you have a week to spend in Greece there are many places that you should not miss. You should begin with a tour of Athens. Other "must sees" are Delphi and Meteora......truly unforgettable. Another popular place is Argolida....with a visit to the first capital of Greece, Nafplio.
I hope this has helped you.
