Freedom of the Seas is now SUPPOSED TO have self serve fountains for the soda package, which I saw here.
I'll find out if this is true when I go on my cruise. I probably won't get the package, but if I see it, I'll let you know of my impressions.
Supposedly, there is a "chip" of some sort in the soda cup that is provided when you get the package, and that activates the fountain when you put your cup under it.
