That’s right, so if I’m planning on purchasing/upgrading a drinks plan, I wait until day 3. Embarkation day is shortened but you’re charged the full amount, second day is often captain’s party with open bars, so day 3 I mosey along to purchase or upgrade my drinks plan.
Here’s another difference between Celebrity and O: when there is an open bar, you actually can get a drink. It was always so aggravating on celebrity. The bartenders were completely rushed off their feet and bar service was abysmal.
