Here is a discussion of that dish from the review on the wdwinfo.com website:
"The baked macaroni and cheese was less successful. I think this was more because I was expecting a more Americanized dish. This was large pasta tubes cooked in a cream sauce and then baked with a layer of gruyere on top. The dish was very, very rich and filling but if you have your heart set on something more traditional, then you might be disappointed. Please understand, it wasnt bad, just not what I was expecting. A portion of this entrée was left behind."

So it's clear that we're not talking Kraft here, which may be just what you are looking for.
