Travelling to SPB June 2018. Wanting to see a ballet at Marinsky Theatre can you tell whether travelling from Sennaya Sq to Teatralnaya Sq. the K186/K350 mini bus and Bus 70 and 71 how often do they go and what time do they return to the square at night. Any other suggestions on getting to see a ballet, for two old pensioners would be greatly appreciated.
Thanks in anticipation
