Yes, they're very quick with decisions. But in visiting the law school I have to say that the admissions office just seems to be really on the ball about everything. They really have their sh*t together. I think they are used to having to work hard for applicants because of their competition from FSU and Florida for in-state applicants. Over 70% of the law students are from out of state. In any case, they really went out of their way for me when I visited.
And even though I know that the admissions office doesn't necessarily represent the law school as a whole, I think it can be indicative of a culture within the school. When you visit a school and see an admissions office that is runs so well, and you don't see any other red flags (in interactions with students, professors, sitting in on classes, etc) you can get a sense of the culture of the school and the adminstration.
And the administration does matter. It matters when you're looking for a job (career services), when you're an alumnus (keeping the repututation strong), and it matters when you have to deal constantly with the administration as a student.
I have been to schools where I was less than impressed by the admissions office (e.g. Case Western) and schools where I just got the sense that they didn't quite have their sh*t together. Neither wants me to be a student at those schools.
If I don't end up going to Miami it will only be after a hard decision. It's a big understatement to say the school impressed me (and it doesn't hurt that they probably have the most beautiful campus I've ever seen).
