I had a discussion with a professor about this the other day. What is the difference between theory/ cultural studies and trad. literary studies when the latter is increasingly invested in looking beyond literary works to discern stuff about the books anyways. Cultural Studies=everything is pretty much a text right? And literary studies= literature is the subject, and everything else is important for the ways it shapes/ defines/ influences literature, blah.
Well last year I tried to go the cultural studies route, and as you point out there are few schools, relatively speaking, that offer this as a specialization. For my SOP, for instance, i tried to say that I was pretty much interested in a lot of stuff--the a-conventional, unique mindset type of guy. I think I went wrong in this sense, meaning I tried to curtail my interests to Cultural Study specific stuff, when in reality, even in cultural studies you have to narrow it down.
With that said, I will get to your question. The few schools that do offer Cultural Studies seem to be those middle of the pack ones that are appealing to a lot of people because they figure they are neither aiming too high nor too low. These schools end up being actually more competitive because of this, and also because they draw in people from a range of interests. I have no idea what your credentials are, but in my focus I am narrowing down my interests back into the literature specific realm and from there I will hopefully be able to culturalize my specialty. There are many literary programs that have extremely large and diverse faculties, and I figure I will not be precluded from exploring my non-conventional interests once I get in.
Anywhere you go you go there will be high exposure to "theory."
Disability Studies is an interesting field, and sometimes it falls under American Studies, another option you might want to consider.
With that also said, here are some cultural studies-ish schools.
Pitt
Carnegie
WUSTL
Many of the Suny Schools (Buffalo permits its students a great degree of freedom)Although, there are many many horror stories about this place.
Washington
Stony Brook has a pretty popular CS program, and several more.
