We will be in St. Petersburg, Russia, on Aug. 26th and 27th this summer and would love to take the two day "St. Petersburg Delight" Tour, through Insider tours (search for Insider Tours, St. Petersburg Russia). It is an intensive 2 day tour for 8 to 16 people. Cost is 295pp. Trip Advisor rates it as a #1 attraction in St. Petersburg. I have contacted them, and the tour is available, but there must be 8 people signed up. We are 3 so we would love to tour with at least 5 of our cruisemates, but we must sign up soon as they need to process the visa-free paperwork. Go to the tour sight and see what you think.
