DH and I usually sail on Carnival. We always do the stateroom guarantee option. I'm content to get an inside cabin because we're rarely in there so that's what we pay for. The last 3 times we've cruised, we've been upgraded to an ocean view. For this cruise, we paid for an ocean view and will be very happy with that but what are the chances of getting upgraded to a veranda cabin? I didn't see an option for the guarantee although I've read that they have them. I was just wondering what your collective experiences were. We'll be on the Dream if that makes a difference.
