What type of accomodation do you have? I had a lower berth and it was quite quiet. I've also read that it's the most comfortable bed on the train, but that was prior to Prestige Class.
go right to the Park car, because you will only have access to it (during peak season) from 14:00-24:00 starting peak season of 2017, and it is such an amazing car, with plush seats, snacks, and more, there should also be a dome, awesome views
