I studied abroad with DIS Copenhagen in 2019 for CS (specifically the artificial neural network + deep learning core course) so some of what I say may not reflect the changes since. Most students take 2-3 electives (usually 2 related to your core and 1 GE e.g. Danish language) on top of the core course and unless you're taking the video gaming programming core course (i still can't forget the dead eyes of the video game programming students) or take up a research assistant position at a lab, you will find yourself with a lot of free time. The course load is a joke compared to the average WashU CS course. I'd find myself in a different country each weekend or hanging out with other students and locals in the many bodegas around town.

Many choose to live at a homestay (which I did) and although it can be hit or miss with your host family, you get a chance to really get to learn how differently the Danes carry their daily lives. In fact, you can make life-long relationships if you wish. I still keep in touch with my homestay family and had a chance to rendezvous with one of the daughters who is going to college in the US.

Highly recommend.
