The fastest way to reach Moscow's most famous art museum from the Radisson Slavyanskaya Hotel, is to take the metro from Kievskaya Metro Station (a few steps from the hotel) and travel on the brown circle line two stops anticlockwise to Oktyabrskaya. Change there to the orange line and continue one stop north to Tretyakovskaya, which is just over five minutes' walk from the gallery. There are signposts to guide you from the station.
