Falkenberg, Sweden
You'll already be here, so why not check out some sites in the area? It's a cute but small city, and we have a link below for some things to explore in Falkenberg and the region.
Copenhagen, Denmark
There's plenty to keep you entertained in Copenhagen, and you can easily spend 2-3 days there. Here are some guides for inspiration:
We especially recommend taking a stroll around the city and eating at Madklubben.
Gothenburg, Sweden
Check out Sweden's second largest city and Sandra's former haunt. There's an amusement park in the city, several museums (including one with a massive stuffed blue whale), nice places to stroll, and good places to eat.
Kingdom of Crystal in Orrefors, Sweden
If you have a car, take a day trip to a historic glass-making part of Sweden where you can see (and participate) in glass-blowing.
Malmö and Helsingborg, Sweden
Both cities are on the way between Copenhagen and Falkenberg. Collin especially likes the castle in Helsingborg.
