I am planning a long weekend in Dusseldorf in December for shopping and visiting the Christmas Market. Good hotel options would seem to be the Nikko and Radisson SAS, with room prices being about the same (around 115,00 €/night for 2 adults and a 15 year old). Nikko does not include breakfast, but is much nearer the Altstad. However, the Radisson SAS does include breakfast, but it a bit further way. Can anybody recommend which would be the best one to chose?
