Exactly my thought but we do watch/follow a bunch of them so it might be a fun way to see who we can spot. We met the Trackers many years ago at AKL and it was one of the highlights of our kids’ trip!
I was at the opening day of Stella Nova hotel. It was downright bizarre to be surrounded by so many vloggers. Almost all of the tables around me were people posting and talking while they were eating. Many of them looked rather disheveled, especially at breakfast the next morning. Admittedly, I have never understood the appeal. Still, it was an odd look. Numerous people who had not brushed their hair, wearing dirty clothes, etc. were filming and commenting while actively chewing their food.
I've also attended opening day of the Art Festival. Expect to see long lines for the art and artist meet and greets. As with many similar events, the 'best' stuff sells quickly. Some booths looked picked over by the end of the day. A good % of the people buying art were Disney employees/AP/DVC, because they had to show their ID to get the discount. There was a steady stream of people leaving the park with art via the IG exit. (taking it back to their hotel room?)
I do not recall seeing many vloggers, though I wouldn't know any unless they are actively vlogging, or someone else IDed them.
The food lines were not too bad. The art lines were not too bad either, unless you wanted to meet one of the artists. Soe of those lines were long, and appeared to be moving slowly.
Ride waits were also minimal, despite somewhat moderate crowds.
A bonus of going early is that the chalk art, etc are all fresh and new. The CM's were also generally enthusiastic.
