I was in the Public Health program at DIS in Spring 2012. Overall, I thought that DIS is a great program for someone who is looking for a ton of guidance and hand-holding. It was easy to get acclimated with the city and the "campus" (which is really just three buildings in the city). They are well-organized and really know what they are doing. They try to provide students with many opportunities to meet other students and Danes as well as options to participate in cultural events, such as visiting historical castles.
In terms of academics, I really learned a lot from my public health classes -- this is probably true because my home university does not offer them. I know that other students in the program who actually are public health majors said that the information was repetitive, but it was interesting to view it from a welfare state system. My favorite parts of the program were the study tours. I really got a chance to bond with my class (about 18 students) while visiting other countries (e.g. Latvia, Finland, Western Denmark).
Housing - I stayed in an International Kollegium with the intention of meeting other international students, but it turns out that this Kollegium was mostly graduate students who were pretty uninterested in meeting undergraduate students. I was also randomly paired with a roommate - which is always just a hit of miss. The room itself is studio setup, with our own kitchenette and bathroom. They gave us a food stipend card, which surprisingly lasted throughout the semester (so long as you don't use the card to buy alcohol).
Transportation in DK is really nice and easy. Everyone also speaks English -- and everyone will say that Danes are cold and keep to themselves, but that is a vast generalization and mostly not true -- unless you are in an obnoxious group. There is an open bottle policy so you will see many people drinking throughout the day, but they don't get outrageously drunk.
Some Cons: The academic work load is actually pretty hefty compared to some other study aboard programs. The weather in Denmark is only nice in the Summer (which begins in June). The cost of living is extremely expensive.
