We 2 are history both keen on history & wish to see - best/past/preserved/ruined sites places.
Arriving in Greece late July for @ least 2 weeks this year
we will take your advice & travel to the Islands first then 'work' our way back to see Athens & Mainland. [thinking by car after Athens]!
* which Island[s] should we fly to
* which islands carry the most historical ruins
* how long will it take to 'Island ferry hop' back to Athens
* will wil be able to find places to stay as we go - on Islands & Mainland
