I believe the same is true for the official videos of glow with the show for World of Color as well. The downside to these is that any one persons enjoyment of the hat depends on how many people around them are wearing them, and that people that aren't wearing them get just as much enjoyment from the view without paying 25$. As such, to make a film I understand the necessity to give them away.
I'm not sure how well they will go over down in Florida. I would think that with the repeat visitors in CA that if it would work anywhere it would be there...but just from anecdotal evidence and reading around they aren't too popular out there either, except when they are giving them away.
