How much to tip driver?

Thanks for response. First I don't understand why it will start a tipping war. I believe you should tip people who provide a service.
Second, renting a car to drive 3 hours after traveling overnight from Charleston SC to Phila to Athens is not something we wish to do. As 69 year olds we would rather relax for this leg of our journey. Plan to take the bus back to Athens after 2 nights and spend time there, before heading to Mykonos and Santorini.

Yes. We enjoy driving as well. Have driven throughout Europe and UK. This trip we decided to relax more since we are only going for 2weeks. Thanks for all your input. Happy travels 😎

We were thinking 20 Euros, is that too much or too little?

It will probably be easier to answer this when you are 10 miles from your destination.

Apparently you have no problem with the cost of the city cab. If your budget can allow for it then it may be the way to go. Tipping is open-ended. You may want to wait until you get near Delphi to decide if your driver deserves anything extra.

Have you thought about staying in Athens for the night then taking the bus to Delphi the next day? Not sure what the cost would be but you'll probably save a bit on accommodations in the city for the night and get a very inexpensive bus ride and pocket the extra for more Greek food.

The bus to Delphi runs about every 3 hours, takes about 2.5 hours, costs about €16 1 - way. Here's a schedule -- not updated lately but timetable has never changed in 20 y ears... https://www.athensguide.com/practicalinfo/busschedulesB.htm What Original poster may not know, as newcomer to greece is that these intercity busses (called KTEL bus network) are very MODERN vehicles, upholstered comfy seats w footrests/a.c, used by people of all levels of society not as in US... I've done pvt transp to Delphi & this bus, & found it very relaxing. If you don't want to take the express X93 from airport to Liossion st. KTEL terminal, a taxi costs about 50E... taxi from a central Athens hotel in AM would be about €13-14. She & spouse may wish to ride in luxury but €200 can buy 4 nice dinners-for-2 in Athens, more than that in Nafplio. It's all about where you want to spend your money.

We are planning to take the bus back into Athens after 2 nights in Delphi. We are lucky to have the means and the health to travel and splurge. Gone are the days of hitchhiking & camping. I love my life!

Fortunately you have the means to spend the money for the cab so if that's what will make your arrival in Athens and then an immediate cab ride to Delphi the most convenient way to get there then go for it.

I just wanted to let you know there are alternatives to the cost of the cab and a bus trip will not be that much of an inconvenience or hindrance and will save you a lot of money.

However in the end it's your holiday and you should do what makes you happy and provide the most convenient way to travel.

If we were going to tip, we always tip 20%. After all, it is a job that has both boredom and high stress moments. By the way, maybe someone used https://aktis.taxi or no? Thanks in advance.

I have found when I’m traveling abroad that it is ok to tip if the service warrants. I don’t think they expect tips in most European countries so if you give a little extra, I’m sure they would be very happy. 20Euro’s seems fair... but you might consider less during the travel time. I find that if they contribute to my trip in some way.. great conversation, giving tips about things to do, places to go, I’ll show my gratitude with a little extra.

Happy trails!
