I was just there on Saturday for F&W, and stopped by Club Cool. They had most of the flavors, including Beverly. A couple were missing from each station though, sometimes different flavors at different stations were missing. It all depends on how fast they run out. They didn't have that problem though when it was Ice Station Cool, however.
And it's been the same story all summer...it all depends on what runs out, and they don't seem to have a good plan on how to keep them filled.
And yes, the atmosphere isn't nearly as good as ISC. I don't think the music is too loud though...not by a longshot.
This was definitely a change for the worse, everyone agrees with that. But look at it this way: how much do you actually get for FREE at WDW? The fact that they actually provide you with free refreshments (that isn't water from a water drinking fountain) is in itself almost miraculous. Disney doesn't have to do this at all, so I think we should just be grateful that they're keeping it free. But it is a letdown of sorts.
