We are a family of 4 who are looking for others to share a van with while in St. Petersburg, Russia August 7 with Celebrity Cruises ("Century") The cost per van (10 people) is $375 for 4 hours and $700 (not sure) for 8 hours. This is the way to go because you have more control over what to see than if on a big bus. It would be booked through Celebrity Shore Excursions (which I have not done yet) and so it's easy. We have one 19 yr old boy and a grandmother in excellen health, and ourselves. If we could get 6 more people (the van holds 10) it would be quite economical. Thanks for reading this. I hope we can hook up with someone for at least 8 hours.
