I am the guy that snores. I hike with my son,who is used to the noise,so we typically will only sleep in a shelter if there is no one else there,unless the weather is really bad. For those days,I carry packs of new earplugs,and offer them to anyone else in the shelter. I know it is annoying,and I can't help it,so that's the best solution I have found. They are nice to save time or tent setup and teardown.
