Russia on your own. Not smart. Everywhere else, just fine.Ship does provide a shuttle service to a place called "red October" if you have a visa. Getting around in St. P is tough.Roads are the worst. Taxis break down. Lots of nasty folks. Beware. Take the ship's tours. It's safer and more convenient. You don't need a visa if you take ship tours. If you go on your own, be ready for long waits in lines at most attractions. Hermitage- over 2 hours. Very crowded. Ship tours get in an hour before the public.
