We will be happy to use them again. We spent three days with them, two in Istanbul and one in Ephesus. The organizer was great to work with. We had a couple of last-minute changes in plans and he was flexible and fair in accommodating our last minute needs. The guides in Istanbul and Ephesus were great. Both were well-informed and personable. We will be happy to use them again on our next visit to Turkey!
We were able to see a number of excellent historical and cultural sites in Turkey in 10 days. The pace wasn't very hectic and the driving from one city to another was no more than 3 hours.
Do your research, hotel ratings in US are different than Turkey. Give info on interests and research the places they are sending you. We needed to make our expectations and wants clearer to help them help us, otherwise they will send you on a private trip that is the same as the big busses.
