Those are real design flaws re the Toliet and Ladder.I just spoke to a supervisor from MIA, who I know and who is on the train. The "water running" sound is actually the vacuum system for the entire car which likely is located under the bedrooms. The sound bedrooms A and B (and possibly H) are hearing is the flushing at the other end of the car. I can say that there is whole lot of flushing going on right now at the other end of the car. It is quite annoying, in my opinion. My portable white noise machine helped me sleep overnight.
I asked about the ladder. The supervisor knows that it is stored in the upper bunk on Superliners but historically there was a cubby for it on Viewliners. He said the situation is being discussed and there was concern about putting it in the upper bunk for safety reasons (because it had not previously been there). He thinks eventually it will be stored in the upper bunk.
Is it bad enough to make you book a Roomette on a VLI so you have a Private Toliet?
