so we are sailing RCL soon. I am not a big drinker of mainstream  brand soda. I much prefer Hansen's, Izzy or Pelegrino sparkling drinks. are these available as well? 
Would they let me slide if i brought on a 6 pack of something they didnt sell onboard?
I am thinking of bringing Starbuck refreshers tubes also. Would they allow me to bring these?

  I've only found one Island Oasis with a corn syrup type of sweetener in it (something like a banana mix? not sure. not something normal, though); the rest use cane sugar.  (in case that's your reason like it is ours)
