What a weird odorous experience that must have been!
No odor backfires for us. My recollections are that the most negative time was when I slept in coach the overhead lights closest to the train's doors never dimmed. This put those who chose seats at the front and back at a disadvantage if they didn't use a sleep mask. I packed my mask in my suitcase and wound up throwing my shawl (bought one instead of a poncho; very versatile article) over my face, LOL.
There was no designated quiet car for this train but I found my fellow travelers not interested in overly loud communications during the sleeping hours. Guess we were all tired and/or understood etiquette
. I also noted that for this train the coach cars had seats modeled after the Acela business class cars; nice recline for feet and head and wider seats. Unfortunately only one recharge outlet per half row so if you scored the window seat life was good. Sitting on the aisle side? You need an extra long cord (7 or more ft) to access the window outlet assuming your seatmate isn't using it.
We ate in the dining car once and had breakfast brought to the roomette by the steward once. Our first meal was dinner and I found by choosing simply prepared food we took no chances. The others ate steaks, had salads and sides; I opted for a fish filet. Everything was prepared as requested (so nice when a cook knows the difference between medium rare and medium). We were seated with a woman traveling alone who regularly traveled this route so she was filled with insider tips for the train and our destination; made for a congenial meal. Breakfast was pancakes and sausage for one, oatmeal for another with yogurt and fruit. I filched the unwanted yogurt included with the oatmeal order and was happy. Self serve coffee and tea was available at the end of each sleeper car 24/7 and a steward was assigned to each car to keep the beverage station clean, refreshed, and respond to any requests you had.
There is no public bathroom in the sleeper cars (there were 4 or 5 attached to the overall train) so when you need to use the facilities everyone else had to leave the roomette. I was on the tail end of a gastrointestinal disorder soooooooooo the others spent a bit of time sitting in the cafe car or standing outside our compartment, LOL. This is where a family rm has a definite advantage over the roomette. I did note families w/o a family rm reservation who rented 2 roomettes across from each other. This solved a lot of problems.
We were quite comfortable in our cots, no sliding in at least the bottom cot but neither adult slept in the upper; that was the domain of our DGD who needed to be pried out of her hidey-hole. No problem reaching her spot since the way up is intuitive.
This train left on time but lost a good hour or two at the stop before Kissimmee ; next time we do a train trip to Disney we may well just deal with the mob scene and get off there since we could have joined the hordes and reached WD from there.
All in all, a pleasant and leisurely start to our Disney trip and the man is looking forward to another roomette experience.
