NY Times 'Frugal Traveler', Lucas Peterson does A $1,000 Day in Moscow for $100.
I asked him (the chief concierge at the Four Seasons Moscow) to create a day itinerary for a hypothetical high-spender that would total roughly $1,000, or about 63,000 rubles (at the conversion rate during my visit). I would endeavor to recreate the spirit of that itinerary on only $100.
