OK, at the drink stations in Cabanas there was orange, apple, and an orange/mango/passion fruit mix (my personal favorite).
At the drink stations poolside there was Minute Maid Light Lemonade and Minute Maid Light Pomegranate Lemonade.
Of course, in the dining rooms/lounges you can order other stuff (on the last breakfast menu they had orange, cranberry, prune, grapefruit, V-8, apple and tomato).
In the lounges there would probably be a cost. You can get apple, orange, and grapefruit on the room service breakfast menu, maybe others.
