This is very true and definitely would cover the single person vlogging the parks. What I think is more valuable is having a family experience the parks and resorts. The Trackers are not that family because they aren't doing anything most families that take a trip to Disney do. What would be really cool is inviting 3 families out each month, having them stay at typical resorts for different families, typical park days, attending special events, then have a Disney editor create a vlog showing their experiences over a week. Could even show them prior to the trip doing their trip planning, fastpasses (Genie, whatever).
I would love to watch something like that, like a mini reality show each month, rather than PMM or PCD or T&J going to Disney Springs or Magic Kingdom for the 100th time.
