I, like bosco, offer no suggestions for what to do. Do you have a guide and such to show you around the school? I don't really know how admitted student days work. Also, do you know what class you'll visit? Not many people have Friday classes, at least past 1L, and I suspect that the last class of the quarter will be very sparsely attended, unless it is a review session, in which case attendance should be a lot better.
Also, I hope you enjoy visiting both schools. They're both great places, and I'm sure you will be happy, and end up with the type of job you want, at either school.
