There is no difference with MK views when it comes to view of the parking lot. They all have the same view. All the MK view rooms are on the front of the building, they all look at the same parking lot. The thing with it is, you don't notice the parking lot that much because it's directly below you. If you look straight down, than yes you'll notice it, but if you look straight out you won't notice it at all. That goes for all of the MK view rooms in the tower. I never heard ANY noise from the parking lot. We were on the 9th floor. My mom is in a wheelchair & CR is the MOST convenient for this. You just go out you room, get in the elevator, get out of the elevator & there's the monorail. If you need the bus, you just go down the elevator & then it's right outside under a covered walkway. That's another reason why I loved CR. You never had to go outside, so if it was raining it wasn't a big deal until you got where ever you were going, unlike at Poly or GF (unless you in the main building). When we stayed at those resorts it was always a walk outside in the elements to get to both the monorail & bus stop.
IMO, CR has the best MK views. GF is hard to get & when you get it, the castle looks so tiny. Poly the same thing really. CR is the only one you can really see the whole park. I love the view there.
