Where does my ship dock in St Petersburg, and how does that affect my stay?

There are currently five possible locations around town where sea cruise ships may be docked, with varied degree of accessibility to/from the city centre. They are:

1. The English Embankment
2. The Lieutenant Shmidt Embankment
3.The Main Sea Passenger Terminal
4. The Industrial Port, berths 32 and 33.
5. The Marine Facade terminal.

The first one is best - it is walking distance from the city centre, in a beautiful setting among historical buildings. Alas, the berth is too small for all but the smallest cruise ships.
The Lieutenant Shmidt Embankment is not much worse, right across the river from #1, great views and a short taxi ride to anywhere central.
The Main Passenger Terminal is farther away, but once you've cleared through immigration there are taxis ready to take you to town, and there is a public bus stop nearby if you feel ready to tackle the public transit network with no signs but in Russian.
The Industrial Port is the tricky one, located around 7-8 km from the city centre, its territory off-limits to all except cruise passengers and crew, plus a handful of 'insider' taxis and travel agencies' authorised vehicles. More info on all these places on our forum.
