As of right now, several sources have conflicting information. People on facebook and twitter have received confirmation that the glitch WILL stand and others have been told that they will cancel and refund the error. However, nothing has been officially noted about the glitch so it will be interesting to see how they handle the situation. I booked it as well for my 2020 sailing but I am afraid to even get my hopes up honestly. However, in the bottom of my email confirmation it says
"Beverage orders cannot be modified once a payment has been made. To change an order, you'll need to cancel it first and then make your purchases again. Bottled juice and water packages will be delivered to your stateroom on the date you have selected for delivery. Wine packages will be confirmed onboard by your dining room waiter. For Unlimited Soda packages, the Coca-Cola® soda cup will be delivered to your stateroom on the first day of your cruise vacation."
So, to answer your question in a short and simple manner. Time will tell and no one knows anything! LOL. ?
