What is the truth on the discount for drink package pay in advance or on the ship? in Royal Caribbean Discussion Posted July 13, 2017 · Report reply Thanks so much. I think that the 30% off would make it somewhat affordable. Even with our Diamond Plus, you still have to wait until evening to get drinks, and on Labadee, it can get pretty high drinking Labadoozels. LOL. I will keep checking on my cruise planner every few days as well.
