Peter, You will be pleased to know, the city's transport network continues to offer excellent value for money. Copehagen Cards can be purchased from Tourist Information Offices and are valid for up to 5 days, affording free entry to around 87 local attractions. Kronborg Castle, Elsinore (a 45-minute train ride away)... world famous for being the setting for William Shakespeare's 'Hamlet' and the nearby Maritime Museum of Denmark appealed to me, while the peaceful tranquility of the much closer Rosenborg Castle gardens were more suited to Myrna's tastes.
Oh we did ... and BEST of ALL, I discovered we could fit~in a short return sea crossing from Elsinore (Helsingore in Danish) to Helsingborg in Sweden, so two countries this time instead of just the one!
