We are going to Moscow in 2014. We are able to get a free visa support letter from the hotel we are planning to stay at only for the first few nights. We are then planning to move to another hotel, but don't know which one. We will be in Russia for about 1 week. Does anyone know if the visa support letter from our first hotel will work for the whole week? We would like to travel without a totally fixed itineray. Will this be problem when registering at other hotels or when trying to leave Russia? Any information on this would be appreciated. Thank you.
