Honestly, we flush them. This is the first time I have admitted it thanks to the anonymity of the internet, but super stinky diapers get flushed down our hotel room toilet. This started about 4 years ago when we had only 2 children (4 now). We were in Chicago staying at a cheap hotel with outdoor entry, it was snowing and subzero temps. We were driving to see family in Cleveland when the weather made us stop unexpectedly and take a hotel room. My wife had changed both kids as she was getting them ready for bed. Both diapers went in the room garbage as usual. This is still how we dispose of most hotel room diapers, but after about 2 hours the smell coming from my oldest sons diaper, around 3 then, was unbelievable. I bundled up to go find an outdoor trash to throw the stinky diaper in, but after failing to find one and almost freezing, i headed back to the room with diaper in-hand. Stinky diaper joined the other diaper once again in the trash, but only for less than an hour. I wanted to open the front door and throw it out, but my wife wouldn't allow it. So, i came to the conclusion that we would unroll the stinky diaper bomb and flush it. We had never unrolled one before, or since, it was a poop smelling nightmare. I flattened it out and put it in with poopside down and flushed. It disappeared immediately. Room started smelling better right away. Every since super stinky diapers go straight to the bathroom for flushing and not the trash can. I know, we are terrible. Try it, it works.
