Hmmm, I think it was their tour #1, but in any event, they have one-day and two-day combinations. The website is www.alla-tours.com - take a look - all of their guides speak excellent English.

In one day we saw so much: Catherine's Palace, the Peterhof Gardens & Fountains, the Hermitage Museum, the subways and Nevsky Propekt, the Neva River and various surrounding areas, fountains, statues, etc etc. We really liked that our tour group was just us - they did add one other couple (with our approval) so we had a total of 12.

We got back to the ship around 6:30 pm; others might add an evening tour, too, but we were exhausted and happy to relax on board.
