Son recently enrolled at U of F. The campus is hugh so don't expect to see it quickly or in detail. Wear good walking shoes as it is a very walkable campus. The are several pieces of interesting architecture and statues. The Bat House is a neat place at sundown when the bats fly out. There is an interesting nature trail (bring bug spray). There are several museums and displays of special interest. The campus has an interesting mix of new and old which should attract a wide group of interests. Parking can be a bit tricky when classes are in session. The length of you stay will depend entirely on how long you want to stay, from a couple of hours to a full day. And where there's college students there's always food (cheap and plentiful).
