Some added thoughts on noise....we just returned a couple weeks ago. Construction noise (from Contempo Cafe) was never really a problem for us. It mostly happened during the day while we were out anyway and they were finshed most of the major work I think. BUT, we were on the 9th floor, next to last room from the end, right over Chef Mickey's and that was loud. Overall, I would say that the rooms at the hotel were very quite - we could never hear noise from other rooms, outside, or the hallways, but when the annoucement and music started up at Chef Mickey's, wow! We are early risers, so the mornings weren't a problem, but the party lasts until like 10:30pm every night, so every 30 minutes you'd hear the party start and last for about 10 minutes. It was a little annoying when you were trying to fall asleep.
That said - I love the CR and would not hesitate to stay again, even in the same room with the party noise. You just cannot beat the location, the size of the rooms, and the view from the MK tower rooms.
