Horrible, terrible, no good. $208 per person to spend the entire day inside of a bus, museum of church that looked exactly like the last. The state-owned souvenir shop is a huge rip off. The tour guides ripped us off claiming a 5 euro fee to take pictures at the stops, however there was no such fee... they pocketed the money. They delivered us back 1 hour late, as most of the day was spent waiting in line and packed like sardines in stuffy old museums.
I recommend doing a tour of the streets of St. Petersburg and nothing too formal, it was a waste of money and we didn't step foot in an authentic Russian restaurant or on the streets. So disappointing.
