Corfu, Mykonos, Santorini, Olympia - rent a car?
A group of 6 of us are doing a Greek island cruse and were wondering if it made sense to rent a car/van in some of the ports of Corfu, Mykonos, Santorini or Olympia.
The shore excursions are expensive especially when x6 and we would rather not go with the masses. The other option is cabs to town or the beaches.
Any advice? Thanks
