I feel for the OP too. My DH used to snore for chuffing England before he lost 50 pounds, and it WAS his weight. (Still snores now but not as bad...
But yeah, this one time me and him went for a trip to the seaside (5-6 years ago,) and we stopped in a hotel room together. He took a sleeping pill and didn't tell me he had btw! Well within about 45 minutes he was in a super deep sleep and was snoring so loud, that the person in the room next door knocked on the door and complained.
I tried to wake him, but he would not wake I shook him and yelled at him, and he just grunted and rolled over and continued snoring. In the end, I sat up in bed in tears as the 110 decibel snoring reverberated through the top floor of the hotel.
I got dressed, packed my stuff up and went to reception and asked if they had another room. It was £45, but it would have cost £100 to get a taxi home. (It was too late for trains.) I left a note saying 'Couldn't sleep coz of your FUCKING snoring! Got another room; I will let you know where I am in the morning when I wake! I am not having you wake me early when I didn't get to sleep til 1am!' Then I texted him at 11am. (When I woke up!) He looked very sheepish when we met, and I was FUMING that he had taken a sleeping pill. (I'm all right Jack!)
Next trip we went on, I booked 2 rooms for us, and even though his snoring is better now, he still snores, so we still always have 2 rooms. Last coach trip we went on (last year,) I booked 2 rooms, and everyone was taken aback when they realised we were a married couple with separate rooms shock horror! Then after 2 days, this woman (around 55 y.o.) said 'how did you do that? How did you get 2 rooms?' The upshot was that people on the trip (particularly women!) were curious and rather envious that I had my own room LOL. We have separate bedrooms too. Have done for more than a decade. I simply wouldn't be able to sleep in the same room with him now.
