I'd like to take this tour while in St. Petersburg mid September. I e-mailed them through their website and have not heard back and there are no 2017 reviews on them on TripAdvisor. Are they still operating? I'm not one for tours but I'd really like to do this one. If not, has anyone done the "Back to the USSR" tour with Marie Rose tours and if so, any feedback? We used Marie Rose last year on a private tour to Peterhof and Pushkin in one day and they were excellent. Thanks in advance to all!!
