The icons, detours, neighborhoods, and experiences that can justify a place in the trip.
THE SHORT ANSWER
Keep the centre, fortress, art and western coast as separate days. Day 1 is a standalone city-and-sauna day; add Suomenlinna for a weekend. Days 3–4 extend to art and the western parks. Change the order around museum closures and put the island on the better weather day.
