We are a group of 8 people. Two families of four with teenagers. We had a wonderful day visiting Delphi and Thermopylae. Tas, the guide, picked us up on time. He is very friendly and thoughtful. We just had to sit and relax. The van was clean and there were bottles of water and even some cookies for us. The trip takes three hours each way, but it us definitely worthy. Not only the oracle itself but also the landscape is impressive. Lunch was also very good. Tas had also made a reservation at a restaurant. Our table had really nice views.
