The promotions all center on the same premise — choosing a perk that you would normally pay extra for — with slight variations. Norwegian Cruise Line's "Free at Sea" promotion lets you choose among five perks (drinks, dining, gratuities, Wi-Fi, and third and fourth guests sail free), while Celebrity Cruises' "Go Big" lets you pick one perk among a classic beverage package, unlimited internet, prepaid gratuities, or up to $300 onboard credit. Carnival runs "Pick Your Gift" offers that could include choices such as a $50 onboard credit or a cabin upgrade. Oceania's "OLife" includes internet access plus the choice of shore excursions, a drink package, or onboard credit.
Princess and Holland America also run similar programs, but include all of the perks instead of making you choose. Princess's program, called "3 for Free," includes onboard credit, gratuities, and a stateroom location upgrade, while Holland America's "Explore4" covers a beverage package and dinner at specialty dining spot Pinnacle Grill, plus a discount for third and fourth passengers and a reduced deposit.
The level of stateroom you book also determines how many perks you receive — or if you receive any at all. On Norwegian, however, even those who book single cabins and inside cabins can choose one perk. And if you book a suite or a room in the Haven ship-within-a-ship, you'll get all five. On Celebrity, you have to book an ocean view stateroom or above to choose one offer, while suite passengers get all four.
