5 days in Russia, need recommendations on how to split time
So I have 5 days in Russia this September (flying into St Petersburg and flying home from Moscow) and was hoping I could get some tips for an ideal itinerary. My thinking was 3 days in St Petersburg, staying in the state Hermitage hotel and 2 in Moscow, but I'm open to anything. Any thoughts on which city is better? Should I even bother with Moscow? And for getting between the cities do folks recommend the red arrow sleeper train or the bullet train? Budget isn't a big deal, it's more about the experience and maximizing our time there.
