Hello, in the Fall I will travel to Greece, flying into Athens and
heading to the Pelopponese by car, for maybe 10 days.

There are several car rental places at the airport: Avis, Budget,
Hertz, National/Alamo and Sixt.

Can anyone recommend one more than the rest? I wouldn't be buying the
high-dollar collision damage waiver.

I would avoid the high-price rental chains found at airports.
Independent rental agencies in smaller towns are much cheaper. Plus,
you don't want to navigate the Athens metropolitan area by car if you
don't have to.

Here's what I would do in your situation:

Take the express bus from the airport to Syntagma. Cross the street
and take the Metro to the Larissis train station. Take the next
"Proastiako" train to Corinth. Rent your car in Corinth. (This is a
cheap and convenient route.)

You are taking no more luggage than each person can carry/drag in one
"lift," right?

But, bus transportation is good throughout the Peloponnese. If it were
me, I'd take busses in the Peloponnese and reserve the cars for places
like Crete or Halkidiki.

All this assumes that you don't run into strikes and/or riots. In
Greece these days, you have to have a Plan B for everything. That's
why it's not a good idea to make car rental reservations (or
reservations for anything, for that matter) too far in advance.
