If your flight arrives in Athens in the morning but you can't check into your hotel for several hours, jump right into sightseeing with a private tour that departs right from Athens International Airport. Stow your luggage in a comfortable vehicle and set off on a custom introduction to the Greek capital’s top sights, including the Temple of Zeus, Piraeus port, and the former Olympic Stadium. By the time you get your room key, you'll already be oriented and know where you want to head next.
