Amalienborg Museum

Old wooden beams overhead in a 1787 warehouse on the quay, a loft family room for two adults and two kids, and suites looking out over the harbor.

Fetuses, skeletons and human remains collected since the 1700s, an exhibition on the gut and the brain, and a treasure hunt through the museum.

Danish design in the old 1757 Frederiks Hospital, free under 17, with a sculpture garden where kids may climb the 'Playmates' figures.

Rooms look across the harbor to the Opera House and Langelinie pier, and the Kyssetrappen steps down to the water are right out front.

Canal trips in small boats that take 12 people at most, on routes past Christianshavn, the Opera House and the Little Mermaid.

An hour on the water from Nyhavn past the Little Mermaid, Amalienborg and the Opera House, in open boats or covered, heated ones when it's cold.
