Is there an extra charge if I have a lot of suitcases?
No, there is no extra charge as far as they all fit in one vehicle. Feel free to inform me in detail about the size and quantity of your baggage as we might need a second vehicle in case they exceed the available physical space.
Is there a fee in case i change the date and/or time of my arrangements?
No, there is no fee for alternating your plans and arrangements as far as I am duly informed. Communication in advance is essential and I am willing and flexible to adjust my schedule to be able to accommodate your revised itinerary.
I would like to prehire you for my transportation from the port of Piraeus to my hotel in Athens and the next day for a day trip to the archaeological site of Delphi. Do I have to give you an advance?
Here is no need to pay me in advance. It is perfectly fine to pay me at the completion of each ride or trip.
