I am interested to see what Imagineering comes up with. There is a lot of pressure on them with this one.
That said, there is no restaurant close by to retheme (like in Disneyland), and if they really want to win over the vloggers, they should drop 3-4 1926 themed ODV/food trucks around the rides entrance plaza with Tiana's World Famous Beignets/Chicory Coffee all day. Bananas Foster Beignets, Gumbo, Crawfish Etouffee, and Muffuletta Sandwiches after 11a. Essentially a 1926 N'Awlins Food Truck Plaza.
If they wanted to be a little bit extra, a small Zydeco live music group (similar to Dapper Dans) would really would bring "The Disney Difference".
