I have never stayed at either one, so you will probably get better info from someone who has stayed at both. However, I've spent a lot of time visiting both resorts, and I personally like the ambience at the Poly much better. The view from the towers at the CR wold be great, but I still like the poly. The CR seems too cold and sterile to me, I like the meandering resort feel of the poly with the lush greenery and the tiki lights. It's just a personal choice.
