We were in port from 7 am until midnight.
I highly recommend getting a private guide here. You can only disembark if you have your own visa, are on a ship tour or with an authorized guide. Problem with the ship tour is that you have to go back to the ship right after the tour. There is an evening tour to the ballet as well. There was a Russian Folklore show brought on board that people enjoyed, but we didn't see it.

We were looking for a Jewish themed tour. This was our itinerary
8.00-9.30 first drive around the city to give you the first impression of it
9.30-11.30 Hermitage museum. Early admission (I highly recommend early admission here! It gets packed and very hot!)
11.30-12.00 hydrofoil to Peterhof
12.00-13.30 Walk around the famous park with fountains, visit to Monplesir, a small palace on the grounds. (Peterhof was GORGEOUS!)
13.30-16.00 drive back to the city. Matroyshka doll master class on the way. We painted our own nesting dolls.
16.00-16.50 The Russian Museum of Ethnography. An exhibition "History and culture of the Jewish people on the territory of Russia" Well worth a visit!
17.20-17.40 visit to Synagogue
dinner at “Hutor Vodogray” – restaurant with Ukraine and South Russia traditions. DELICIOUS!
Evening program - ballet “Swan Lake” in Alexandrinsky Theater
We both loved St Petersburg! So much to see in so little time! We bought lacquer boxes and Matrouschkas (nesting dolls)
Note: do not buy amber here! Too expensive!
