We didn't hear the monorail from our room in the North Wing at all. Note that the only way you can view the castle from the wing rooms is if you also have a view of the parking lot. The garden view rooms face the lake. You might have a better chance getting a renovated room in the South Wing though the North Wing is much closer to MK and the food court. We liked having a ground floor room because it has a patio. The upper level wing rooms DO NOT have balconies. We did have to wait a few hours to get into our ground level North Wing room though we checked in early. You might want to plan accordingly, so if the room you want isn't available at checkin you can just go to MK while it is getting ready.
