Day two: Heineken Experience (4-floor brewing tour + tasting at the original brewery), Brouwerij 't IJ (the windmill brewery). Day three: ruin bar Café de Dokter, Red Light District walking tour (legal model, educational framing), countryside windmill bike day to Zaanse Schans (45 min train). Sleep at the Pulitzer Amsterdam (canal-house conversion) or the Dylan Amsterdam. Schiphol (AMS) is direct from major hubs.
