On the first day they give you a placement test for beginner, intermediate or advanced. They also are full on immersion. There is no English (or other languages) spoken during class. Most of the ones I've been to have daily handouts rather than books which include grammar, exercises and articles to read (depending on the class level). The class also includes a lot of conversation. I think they work because the classes are usually small (max of 12 students at most schools) and it focuses on conversation rather than being overly structured. They aren't actual courses though. You can take as many weeks as you'd like.
This is how it worked at my school in France. I was probably a B1-B2 at that point and tested into the second-highest level they had, but it was all a rolling curriculum, so you basically just join a group.
I wouldn't call this setup "fuzzy", though, especially at the B1-B2 level - in my experience, it was perfect for me and my level/needs. I didn't need new grammar concepts introduced to me, I needed to learn how to use what I already knew. My French improved leaps and bounds.
In the beginner classes, they took the group through a series of day-to-day situations, teaching speaking/reading/writing/grammar/pronunciation along the way. This closely mimics how children learn languages, as far as I understand - there's no set curriculum when you're a toddler, you just sort of learn new things as they happen in your environment.
