so, for someone who is totally NEEDING a diet coke fix every, say, hour.... what soda can you get (and when/where on the ship) using the fountain card? What is the cost? If it's the wrong "kind" of soda available, can you take your own onboard?
(this is actually not MY question - I'm not too big on soda. But apparently if you're a real Coke affectionado, Pepsi just won't do, lol)
