The hot chocolate at Disney for the most part is as bad as their coffee. It has canola oil, corn syrup, and a bunch of other garbage in it. You can check out the ingredients on one of the tins of it that they sell.
I think, personally, that some form of chocolate or cocoa should be the main ingredient in any hot chocolate, not the 4th as it was when I looked at the tin of the Disney swill.
I would stick with the hot chocolate at Ghirardelli unless someone knows of another place that sells real hot chocolate.
ETA: I am looking at a tin of Disney hot chocolate right now. Here is the ingredient list:
Suar, whey, non-fat dry milk, Dutch cocoa, partially hydrogenated canola oil, corn syrup solids, natural and artificial flavors, gum, salt.
To compare the ingredient list on Trader Joe's sipping chocolate:
Cocoa Powder, Cane Sugar, Chocolate Liquor, Cocoa Butter.
