Yes, Dole Whips are available on Disney Cruises, but they are not included in your cruise fare. Unlike on the Disney parks side, where availability and pricing can vary, onboard Dole Whips always come at an additional cost.
You can find Dole Whips at select bars and quick service locations on the ship, often near the pool deck. They are available both with and without alcohol, and both versions are priced separately. Adding alcohol turns it into a popular frozen cocktail option, while the non-alcoholic version is simply a classic Dole Whip treat at sea.
Whether you order it plain or spiked, it is treated like a specialty frozen drink rather than a complimentary dessert, so plan on paying out of pocket or using a beverage package if applicable.
