Spent 3 whole days in port. Did 2 half day and 2 full day tours plus went to ballet one night. Tours arranged by Seaborne were of Hermitage Museum (1/2 day), St Petersburg Cathedrals (1/2 day), Romanov's Imperial Residences (whole day) and Royal Palaces and Parks of Peterhof (whole day). All the tours were well managed with not more than 25 people on any one tour. By going with packaged tours did not have to have a Russian visa (cost over $200). Also were allowed into Hermitage/ Catherine the Greats residence, and Peterhof early before most tourists. Made these twice as enjoyable without the crowds that were coming in as we were leaving. All of the tours were done using headphone systems so you didn't have to be right next to guide to hear but could wander up to 40 feet away and still hear. Meals provided on whole day trips were very good servings of local specialties. Second time in St Petersburg and these tours were much more enjoyable than the first time.
