Hello,
I started a posting a few weeks ago and I asked for some feedback about liberal studies programs in general and the one at the CUNY Graduate Center specifically. I received a couple of replies and one particularly detailed and positive one (you may want to look at that reply under the posting for The Graduate Center Liberal Studies.
After speaking with many people, I have decided to apply there. btw, I live in Manhattan (so this may not be do-able for you) but I wrote to Grad Center's admissions office and ended up being invited in to speak with the assistant director. He was very helpful and he also put me in touch with the head of the liberal stdies program (Prof Daubin) who was also very encouraging. In terms of making your "more marketable as a PhD applicant," Prof. Daubin gave me many examples of MALS students who went on the the doctorate at CUNY and other schools. He was quick to point out that there are "no guarantees" but the fact is that you take courses in the doctoral programs with the doctoral faculty so if you do well, then that makes your doctoral application more impressive b/c you are more of a known quantity. Good Luck.
