I think it would be a good deal if someone had at least two days to look around St. Petersburg.
The card costs 1,100 rubles ($37.50), and gives free admission to:
St. Isaac’s Cathedral
The Church of Our Savior on the Spilled Blood
The Russian Museum
The Peter and Paul Fortress.
The price also
includes a bus tour of the city from City-Tour, and is valid for discounts of 10 percent at a number of hotels, restaurants, and shops.
If it included the Hermitage, Peterhof and Russian Museum entrance fees it would be great!
