RISD (Rhode Island School of Design), MICA (Maryland Institute College of Art), and the Art Institute of Chicago are pretty much the top three.
RISD's by far the most famous (and pretentious). They pick your own schedules for you, though, and are somewhat renouned for putting out cookie cutter artists.
I don't really know anything about the Art Institute of Chicago.
SCAD (Savannah) is not that good of a school... but they're one of the biggest. So they're well known, just not in a good way

Not that they're bad, definately have her apply, because they have about an 80% acceptance rate.
I'm in my last semester at MICA right now, which is a pretty good school. I don't have anything bad to say about it at least (with the exception of a couple teachers...

). We're going through an expansion process though... when I was a freshman, the acceptance rate was only 40-50%. The freshman class this year is maybe 75% bigger than mine was... so now it's definately more like 70-80% acceptance. Whether that's a good thing or not I don't know, we're hiring more teachers and such, but the best teachers are now spread thinner (although the bad ones are, too, by that logic...) and I don't know if incoming freshman will get as much individual attention as I recieved.
One thing to take into consideration is what your daughter wants to do (if she knows), and how easy it will be to switch if she changes her mind (odds are she will... almost everyone I know did... including myself) So keep that in mind when looking at a small school or a state school... sometimes they have a really good, say, painting department... but if she decides she wants to do illustration she may end up having to transfer, which is really hard both financially and socially.
Oh, another thing she may be interested in (and probably less you) is going to school abroad. One of my best friends from high school goes to school in Edinburgh, Scotland. European schools are so much cheaper that even with airfare twice a year it's cheaper. If she's into it (and you can deal with it), it's definately an amazing experience.
