No juice but you can fill it with plain, unsweet iced tea and lemonade as well as blue poweraide. I was in the same situation, not really soda drinkers and debating if we should buy them or not but one evening early into our last trip we were outside and all a little chilled from swimming so much so I bite the bullet and bought one cup to fill with hot decaf coffee for my hubby.Then my son took it over the next morning, washed it out and used it for hot chocolate, iced tea, lemonade etc. We even filled it with ice water a few times for car rides. This one cup ended up kind of being his little mascot, it went everywhere with him even though he is 16, LOL. I feel with probably got our moneys worth on the third day and we were there 7 nights. The one thing I didnt want to do was bring it down to the pool or beach for fear it might get misplaced or stolen because we were usually all in the pools at the same time. You can keep you receipt and if that does happen they will replace it.
As far as prices for coffee, I think it was $3 and $5 per cup depending on if you wanted Kona coffee but they do provide you with a coffee maker in your room and a started pack of pretty decent Joffreys Kona coffee
