So from what I’ve read here and elsewhere, the California Zephyr doesn’t have a 0530/0630 car, and the sleepers start with 0531/0631. So the 0532 would be the second car from the diner. Does this sound correct? This might help me with my upcoming trip.5100 is right next to the dining car and Roomette 1 is in the middle of the car, so I don’t see any reason why you’d want to change that. On the Zephyr, you are correct that 0532 is the third car from the diner, so you may want to call and see if you can get moved to 0530. As to Bedroom D, there’s nothing particularly good or bad about that room, but Bedroom E seems to be the room of choice for manu AUers, as it’s in the middle of the car (which means a nice ride), is right next to the beverage stand and stairwell, and is only adjacent to one Bedroom (instead of two). Room A does have the benefit of being the only Bedroom which is not connected via partition to any other room, which means a solid wall with less noise, however it has less floor space and is at the end of the car, meaning worse ride and more truck noise. So yeah, I would say that you may want to call and see if you can snag Bedroom E in 0530. If that isn’t available, it may be a matter of figuring out if you care more about being in a sleeper close to the dining car or having the best room. Good luck!
Thanks!
