Each gateway city runs regular guided group sessions — a morning walk through the monumental heart, a market or workshop at midday, monuments with timed entries handled for you. Groups stay small enough for one guide's voice (about thirty people as the practical ceiling), and the session is the unit: you can take one day in one city on its own.

Evenings carry their own options — night walks, viewpoints at sunset, music and dinner routes. Day and night sessions combine into a full city day, or stand alone as a single booking.
