Mere Sverige (More Sweden) is a tourism promotion site for Sweden aimed at the Danish market. The site is therefore in Danish. More Sweden uses Google Maps to provide Danish visitors to Sweden with all the accommodation and sightseeing information that they will need.
The map includes some very nice features. In particular the numbered marker clustering solution is well thought out. Numbered markers show the number of points of information at a location. If you mouse-over the marker a small information window opens with preview thumbnails of the individual locations. If you click on the marker the map zooms in so that you can view the individual markers.
Markers on the map are divided into the categories of 'experiences, 'accommodation' and 'transport' and each of these categories is further subdivided. For example 'accommodation' contains sub-categories of hotels, B&B's etc.
