Should I buy the Copenhagen Card?

If you plan to visit a lot of "attractions" included on the Copenhagen Card, then it can be a great deal (and just simplify your visit) since it also includes public transportation. I would use the "Savings Calculator" tool on their website after you've planned your itinerary to help you decide if it would be worthwhile or not. For what it's worth, my family got the Copenhagen Cards the first time they visited Copenhagen and were really happy with them! On subsequent visits, we didn't do as much "touristy stuff" so they haven't bought the cards again.
