a business programme in the government quarter, a culturally led stay near Museum Island, a later-hours visit built around Kreuzberg and Friedrichshain, or a quieter stay in Prenzlauer Berg can each justify a different shape of day. The point is not to fill every hour, but to give the central experience an honest approach and exit.
Once one district, reservation or hosted moment is allowed to anchor the day, the city has room to be encountered rather than merely crossed.
