Taking a tour at the beginning of your stay in Athens helps orient you to the capital city of Greece. This one gets you to and from many of the major sights easily in a short amount of time; some you may want to revisit on your own later in your stay.
Cape Sounion is a dramatic location at any time of day, but most of the afternoon tours schedule it so you'll be there for the amazing sunset. Beneath you the Aegean Sea stretches out, glimmering in the sun; beside you stand the stately ruins of the Temple of Poseidon. It's easy to understand why the ancient Greeks built a temple to the god of the sea here.
Cliché phobic? Independent traveler rather than a tourist? Then this one isn't for you. You get to see the lights of Athens, look at the picturesque harbors, and then go into the Plaka area of Athens for a pre-canned dinner and show. Yet it's mindless fun, less trouble for a tired tourist than finding a unique place on your own, and nearly an essential experience for a first-time visitor to Greece.
Organized trips to Meteora make great sense - it's a long drive into the mountains that most casual travelers won't undertake on their own. This one includes a stop at Delphi as well.
Personally, I think a visit to Delphi is as essential as a visit to Athens. This beautiful, historic, and inspiring town on the slopes of Mount Parnassus is a great experience. Have extra time? You can turn it into an overnight trip and, with an early call, you can explore the site without the crowds early the next morning.
