I have had it work once in the US out of more than 10 attempts. It did also work on a cruise ship, which was good because kids had hit all the floor buttons and run. Double tapping or holding a lighted button works to cancel all the time in Japan. There are other button codes. Once, when I was in Japan and we waited at 8am for a lot of full elevators going past opening up the person I got in with (to another nearly full elevator) held down the G button for several seconds, all of the floors flashed and we went straight down without stopping. I asked as we got off, and apparently on other elevators this floor bypass can be done by holding down the close door button the entire trip.
