Same here. We turn the PA off in the room, but I can still hear it in the hallway along with the various hallway noises. I'm a light sleeper. 9:30 was the absolute latest I've ever slept, but that's because I hadn't gotten to sleep until 4:00 or so. I usually wake up around 7:00 because I can hear all of the rustling and bustling.Yeah I get woken up by noises easily. Not talking train noise, but people and the PA, so I'd probably be up early without an issue.
I usually wake up at station stops too, simply because I can feel the train stopping. It's wonderful, though. I love checking to see where we are and then looking at the landscape at night until I get sleepy again.
