I think the difference most people feel is how much effort some of the top influencers put into their work. You can see the work on screen. They hustle. They constantly have meetings and don't sit still. It seems like a fairly hectic lifestyle (the lovely inthefrow comes to mind) so on some level the trips are the result of that.
Brogan is a bit different, as anyone who watches a few of her vlogs can testify. And most influencers don't hype up the trip for so long either, they just tell you in a vlog. But again, it's purely because Brogan doesn't have much to be excited about that people feel as though this has been rammed down their throats.
Personally I don't care, I was just keen that she not be in the same place as me at the same time
