When we flew into Athens in November, we also had the included 3 day land program. Of course, day 1 is just getting there and checked into the hotel. We booked a Tuk-Tuk golf cart tour that afternoon which we thought was excellent and gave us something to do that afternoon and gave us a great overview of the city. As I recall, it was about 3 hours in length and picked us up and dropped us off at the hotel. The hotel stored the luggage for us until we were able to check in.
