Well, I happen to know people in the US military who have been on this vacation since the beginning of the year. I am not particularly social or well-connected, so the fact that I know someone like that means it's widespread. Downvotes or no, that's reality.
it doesn't logically follow from the fact that you know about a group that there are similar groups.
for example let's say you know a few people who work for the military and they happen to work at Area 51. sure lots of people know military personnel, but your sample is still pretty special. without a good representative sample we simply have no idea.
