Tips and tricks to deal with snoring partner

Long story short, hubs and I have opposite sleeping preferences and schedules so we have our own rooms at home and love it!

He has a mild deviated septum, not bad enough to fix. No apnea, doesn't drink or smoke, isn't overweight. It literally is only a problem on vacation when we have to share a room. But we are on day 3 of a 14 day vacation together and his snoring is killing me!

I tried earplugs but they fall out, a fan but it doesn't drown out the snoring enough, and extra melatonin but it still took hours to finally kick in.

Please help!!
