We are a family with a 17 yr old (interested in ancient history) and a 12 yr old (interested in pools and beaches), so thought Greece might fit the bill for us all to find something of interest. We have been advised the southern Peloponnese area might fit the bill. Is it essential to have a car, or could we do the ancient sites via bus/excursions? Any advice on specific locations gratefully received. Also, if any specific accommodation recommended that would be also be gratefully received. (prefer small hotel or self catering, but pool essential, and walking distance to beach and/or shops). thanks!
