I wish could give this 3.5 stars. I was disappointed that I was with one large group on the first day of Delphi Chat Tours and then passed to Go Tours for the rest of the tour. I really wanted to do Delphi again because it was such an awesome experience on a tour I did years ago. This tour wasn't as detailed as it did not include the Tholos even though it was by the same company. WHen I asked the tour guide why we weren't going to the lower site I was told that they only do that on multi day tours. I said that I a on a multi day tour. But because I was with this one day group I missed out. Also My itinerary indicated that I would be staying in Delphi for the day overnight. I was looking forward to it because the host hotel has the most beautiful pool. Instead I was taken to the hotel only to meet up with this other group to a drive to Meteora. By the time we arrived it was late in the evening so there was no swimming for me. The rest of the tour was just great. I got to experience Meteora on clear day. I was here previously and was met with bad weather. The guide and driver were great. The hotel in Thessaloniki was nice though the bed was low to the floor.

We were shunted between 3 different tours. 3 different guides in the first 24 hours. More time driving around Athens picking people up than at Delphi. Convenient for subsidiary companies at the expense of the tourist. My advice, book directly with a company and not with Viator.
