Has anyone been to Greece and if so, did you visit any of the islands? I'd love recommendations on must-see things. I don't mind lots of walking and being out 13 hours a day to fit things in! My trip is set for early Oct and the weather should be nice... just figuring out where to go aside from Athens of course. Thinking a trip to Meteora, Cape Sounion, Delphi, and maybe a day flight to Santorini (but I've read it's probably better to pick another island). So far just tickets to Athens are booked. Looking forward to any tips or suggestions
