That's rather funny. Disney World and all the parks globally together are huge. The overall content is massive, multiplied by 100 if you include the media side, but the vloggers all want NEW theme park experiences (including Downtown Disney and Disney Springs here). That is a very limited product to cover. So of course others are all going to review the same things, in fact they're reading the same sources he is.
It is doubtful that others copy his half ass treks across country mid-pandemic. They won't buy an RV and drive everywhere. I sincerely doubt many of the other vloggers take time to listen to this middle age man ramble on and on, never getting to the point as he wants to draw out the videos to add more commercials. I know I won't. Don't expect them to either.
Re: unshaved/unwashed: absolutely. I swear there were times I could smell his filthy jeans through my monitor
