Just off of QV after enjoying the Christmas & New Year cruise. We always opt for an aft suite and never have we had any problems with vibration or noise,although we do enjoy the noise of the propellers cutting through the water. We have experienced "the smells" which yes,is pretty awful but not much can be done about it but they should be honest with people,and not say......we'll check this out,as I'm pretty sure they've had hundreds of complaints over the years.
