Hotel Sanders

Toys and kids' clothes at Magasin, with a museum of the department store's history at the back of the Kongens Nytorv building.

Thick brick walls from an 1869 harbor warehouse, connecting rooms, and view rooms that look straight onto the water, a short walk from Nyhavn.

A grand old square with a garden at its center, known for puppet shows on the green.

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.

Rooms of record holders, from the world's tallest man to more than a million falling dominoes, plus a game zone with the world's largest Pac-Man.

Dark rooms, optical tricks and jumpy surprises, more of a spooky walk-through than a traditional museum.
