Keep in mind that a cream ale is not really all that "creamy"... Its just a light beer made with some corn - kinda like a Miller with a tad more flavor.
If you want something with a creamy mouth feel you'd be better off with a malty beer like a Scottish Ale, Bock or a Belgian.
I assume you are brewing extract: Northern Brewer has a good smooth Cream Ale kit if you still plan on going that way...
