Yep, I am staying on the Louis Olympia in the Adler Port. All things considered, it seemed to be the best option. Plus, how many chances will you have to say you stayed on a cruise ship in the Black Sea during the Winter Olympics?

To elaborate: If you need to be near the Mountain Cluster, the cruise ships are most likely not the best option. If you need to be near the Coastal Cluster, it's almost impossible to get any closer than the ships in the Adler Port without being in the Olympic Village. Hotels are around the same price as the cruise ships, but locations are generally not going to be as convenient. There is always the possibility that point redemption options become available closer to the Games, but I didn't want to take that chance since some properties (specifically Marriott) aren't even viewable on the website. Some have also recommended Airbnb, but those prices are not regulated by the government and are thus absurd during the Games.
