Janet, We worked with a Greek travel agent and she put together a package price. I know the total that we paid for a family of four for an 8 night trip, and at one time had the breakdown, but I no longer remember what each component cost. Our package included (a) cab transfer from the airport to the Hera Hotel in Athens (b) two double rooms for 2 nights at the Hera Hotel with breakfast included, (c) cab transfer to Pireaus (port), (d) the fast ferry to Santorini, (e) transfer from the port on Santorini to the Traditional Esperas House in Oia, (f) two nights in a Junior Suite at the hotel including breakfast, (g) transfer back to the port, (h) fast ferry to the island of Naxos, (i) a two day rental car on Naxos, (j) two rooms for 2 nights at the Naxos Beach Resort Hotel including breakfast, (k) ferry back to Pireaus, (i) two day car rental so we could drive to Nafplion and then get ourselves to the airport after our stay there, and (j) 2 superior double rooms for 2 nights at the Hotel Aetoma in Nafplion. Our package price for this 8 night trip that included all hotels, all transfers or rental cars, all breakfasts, all ferries, came out to 734 Euro per person, or 91 Euro per person per day. We had never before used a travel agent to book independent (non-group) travel but were advised that this is the way to go in Greece. Ferries can be canceled last minute due to strikes or rough seas. If you have booked a hotel on an island on your own, and are unable to get to it, and the cancellation deadline has passed, you'll be stuck paying for the hotel that you can't get to. If you use a Greek travel agent, they'll cancel that hotel at no penalty and find someplace else for you to stay, and alternative activities to enjoy. Fortunately, nothing like this happened to us, but we were very happy with our decision to use a Greek travel agent. The woman we used was very intuitive. She put together the perfect trip for us after many emails back and forth between us. She was someone I could turn to for information and answers to my many questions both in advance of travel and while we were there.
