I found out I have a $200 OBC for a cruise 60 days out. I have already made final payment and prepaid gratuities with that payment. I also plan to buy the drink package before the cruise. Here is what I want to do, is it possible? 1) Get a refund for the gratuities I already paid 2) Use that refund to buy cheers (along with some extra money) 3) Use combination of OBC and $ to pay for gratuities on the ship. The main blocker is getting an actual refund for the prepaid gratuities. Otherwise, I will not be able to use the OBC for Cheers or Gratuities unless I wait to board to buy Cheers, which would be more expensive.
