A city best seen from a bike, once you get out of the centre.
This is a shape, not a schedule. Each day has two anchors and a lot of slack, because 3-day itineraries that book four things a day fall apart the first time lunch runs long. Move things around freely — the neighbourhoods are grouped so that walking between stops actually works.
Amsterdam's constraint is timed tickets: the Anne Frank House and the Van Gogh Museum release on fixed schedules and go in minutes. Assign one person to the ticket run and keep the confirmed times on one shared plan, because a group of six trying to sync three separate bookings is how you lose a morning.
