We experienced the worst guide in my extensive travels on our trip to Greece. SmarTours should change their contract travel agency in Athens. Our first guide, Gina, was disorganized and droned on forever repeating unimportant information, making most of the travelers tune out. Then she was quite upset when someone missed important information. She lost 3 guests, on the way back to the bus, at the initial dinner in Athens and the entire group was delayed an hour while she tried to find them. After returning from the cruise portion we replaced Gina with a second very good guide, Stratos. However, at the final dinner, the agency sent a third guide with whom we had had no previous contact. The cruise and hotels were an excellent value as was the Emerates flight from Newark to Athens. Excellent itinerary, except a listed stop at Epidaurus, one of the sites on the mainland on the way back to Athens was not made. This had the best preserved Greek amphitheater in Europe!
