jbroadway, here's the page about Cable TV in Lafayette dorms. Cable TV Residence Life Lafayette College
All lounges are equipped with cable TV, at no charge to students.
All dorm rooms have cable access, it costs $108/semester to use it. (Interestingly, my daughter's college gave all dorm rooms basic cable access for free... and she attended a much less expensive college).
This may be something your daughter needs to work out with her roommate. If neither the roommate nor your daughter want cable, then you're fine. But if the roommate wants it and your daughtern doesn't, and the roommate ends up paying the full price but your daughter gets the benefit of watching it for free... could be a source of friction.
My son is a recent Lafayette grad and my daughter attends another college. Virtually every student has a tv in their dorm room these days. I hated that idea when we first looked at colleges for them, remembering "back in my day" when we gathered in the lounges to watch tv. But it turns out the kids gather in each others' rooms to watch sports, movies on DVD, and play video games. They're still socializing, just not in the lounge. I was afraid it would be everyone by themselves watching TV, but that doesn't seem to be the case.
