One day: old Madrid, the Prado after lunch, sunset at Debod
9.30am: Plaza Mayor before the crowds, then the Palacio Real
Calle Cava Baja in La Latina is the tapas street before lunch
Day 2 adds Retiro Park and the Thyssen or the Reina Sofía
Sunday: the Rastro, then La Latina; Reina Sofía free 12.30-2.30pm
Days 4 and 5: Toledo, then Segovia or El Escorial
Never three great museums in one day; every plan in the guide
