I have a flight that arrives 12:30 and then leaves at 21:20 on a Saturday. During this time I would like to leave the airport and visit a site (ie. Kremlin, Red Square) and have dinner before the exiting flight. However, it seems that there is no direct Metro and car travel could take a long time. I'm looking for other traveler's suggestions on my bestr options without threat of missing my evening flight. Thoughts???
