Holland America Line added stateroom gratuities for 2022 Alaska bookings to ‘The Ultimate Upgrade Event’ for one week only, through Jan. 10.

2022 marks 75 years of cruising in Alaska for HAL. From April through October, the line will deploy Eurodam, Koningsdam, Nieuw Amsterdam, Noordam, Oosterdam and Zuiderdam there. Plus, 16 different cruise-tours combine a three-, four- or seven-day cruise with an overland exploration of Denali National Park and Canada’s Yukon Territory.

The Ultimate Upgrade Event already offers stateroom upgrades, reduced deposits, $75 fares for kids on Alaska cruises and up to $200 on-board credit. (Plus, with HAL’s ‘Have It All’ premium pricing package, shore excursions, beverages, specialty dining and Wi-Fi are included.)

This wave season promotion applies to select summer 2022 through spring 2023 cruises booked by Feb. 28, 2022.
