I travel via Amtrak with my sister and so far, she insists on the top bunk as she is more agile. Also, I'm so short that we can put my sister's carry on suitcase at the bottom of the lower bunk and I still have room to completely stretch out. However, she is a very light sleeper and can't sleep when I snore. I do have a device that cuts down on my snoring by quite a bit, but it can also cause me to gag and choke, so I don't like using it. So my question for you all is, if I change to sleeping on the top bunk, will she be able to hear my snoring as much as she can when I'm snoring below? Any experiences in this regard?
