The very good refers to the guides and the hotels. I have concerns about some of the info provided by SmarTours, e.g., about the currency one can use: only credit cards and Rubles can be used. This should be clearly stated in the info which said that Am $ and Euros could be used. Also, the tour was more strenuous than I had anticipated and since most of the group was 70+ (one man had to leave in the middle) this should have been explained. One more thing the four days in St. Petersburg where great but two days in Moscow were not enough. The Golden Ring was not worth it and those two days would have been better spent in Moscow.
