Club Cool is blatant advertising for CocaCola. I can't see how people who are upset about Starbucks (I am not) are not upset about the existence of Club Cool.
As for me, I like Club Cool because it offers free pop. I like free stuff. Other than that, the place seemed completely wrong. It's just a sponsor's store, and outside of offering the round the world beverages, they did nothing interesting with the opportunity, like actually sell the beverage from around the world. If you want to have some examples of sponsor's products around the world, do it right. If you just want to sell coca cola shirts, open a store in Disney Springs and free up Epcot space for something better. A Ghriardeli shop isn't exactly the most exciting thing in the world, but if they pass out free chocolates like the marketplace location, and have the same excellent soda fountain creations, it works.
