I loved the CR and would stay there again if we got another great discount like we had then. We had 40% off and booked a standard view garden wing room, which is the least expensive room on the monorail loop. It was worth it for that price. I would have a hard time justifying paying full price for a tower room, unless it was a very special occaision.
Walking to/from the MK was so convenient. Of all the parks, MK is the one to most likely have a huge transportation bottleneck, since even if you drive there you must wait for group transport back to your car. Only CR guests can walk right back to there room, no matter how crowded the MK is at closing. If I was determined to be in the MK for 4th of July or Christmas day, etc., that would be an occaision where the CR would be worth it to me.
Regarding the theme: My DH didn't care for it. He was OK with staying there, because of the convenience, but he prefers trees, landscaping, nature, etc. He felt there was too much concrete at CR. I let him choose the resort for our anniversary trip next year, and he picked POR. I do think the price has something to do with it LOL, but the natural theming is more his style.
I liked the theme of CR, though. It was very "Disney". It felt very "bustling city", as opposed to relaxing, though.
