I used them at the Grand at popular times of the day like right after park close or lunch there was a bit of a line for their two machines, but nothing long enough that I minded. I could see though how crazier food courts like pop or the all stars it could lead to some pretty long lines. And then when you get the teenagers there for sporting events wanting to try every single flavor..... (not like I would've ever done something like this when universal first debuted them.........) I would be shocked if they put them in the value resorts. I am disappointed they aren't at the contemporary for my next stay, because I am rather fond of the diet cherry coke!
