We were just there 2 weeks ago. Stayed in a Finding Nemo suite. I've stayed in all levels of resort form Value to Deluxe, and in terms of noise I found it no different than anywhere else. We heard some kids running down the halls a couple of times, but I've heard that at all levels of resorts. With 5 people, we had some in each of the beds, and nobody complained of being uncomfortable.
Food court can be busy at times, but we never had excessive waits, and there was always a place to sit. I found it no louder than some of the moderate food courts that we have eaten at.
Buses were very good for us. Morning waits were extremely minimal (never more than 5 minutes), and while the "end of the day" lines were long, we still never waited more than 15 minutes, and they often sent either the double-length bus (I apologize, I can't remember the correct term for it), or 2 buses at once. The only long wait I had was one early evening, around 6pm, heading back from the MK...the wait was about 35 minutes.
My only complaint was the location of the bus stops coming back from the parks. Someone else touched on that, above, but it wouldn't be a deal breaker for me.
