THE SHORT ANSWERReserve one defining morning anchor, then keep the rest of the day in the same part of the city. Choose one fixed morning anchor, keep lunch in the same district, and protect the evening from unnecessary cross-city travel. St Fagans is a substantial half-day and the Bay is a separate corridor. Fixtures can dominate prices, roads and station capacity.
