For two days, read the three-day itinerary before choosing what to leave out. Keep the combinations that matter most to you rather than trying to compress every day. You can return to the walking guide when you need a shorter afternoon, or the food guide when a meal is the main event.
For a longer stay, leave some days less structured. A ferry morning, a coastal walk or an afternoon browsing food shops gives you a different rhythm. There is no need to fill the extra day with a second set of timed bookings simply because the calendar has space.
The three-day guide is the complete multi-day itinerary available here. The other linked guides help you build or shorten individual days; they are not separate one-, two- or five-day itineraries.
