I think Club Cool is a great idea to save a little cash on drinks while you are at Epcot. When I am on a solo trip, I usually will stop in anytime I am walking through the area. But what I have noticed with the new location, that more people jump in front of you while you are waiting your turn. In the old location, where the fountains were set up in a circular station format, it was less of a problem. Now with the dispenser on the wall, people jumping in front of you has been more of an issue, at least for me. Last time we were there, both times we stopped in we were waiting for the family in front of us to finish up and another group just walked right in front of us essentially took over that station. Of course my wife, who is not shy, had to "politely" let them know that people had been waiting.
