Answer: The experts at Holland America Line, the most experienced Alaska travel company, have some tips on packing when you're headed north on a cruise or cruisetour.
Southeast Alaska
On an Inside Passage cruise you will be traveling along the protected waterways of Southeast Alaska, also known as "the Panhandle." The weather here is temperate, with summertime highs usually between 50 and 60 degrees Fahrenheit, climbing occasionally into the 70s and 80s.
North Alaska and the Arctic
If you venture farther north you will find the climate to be drier. Summer temperatures in Fairbanks and other parts of the Interior often reach 70 and 80 degrees Fahrenheit. In the Arctic, for those traveling to Prudhoe Bay or Nome and Kotzebue, temperatures are cooler, in the 40s and 50s.
General Packing
Alaska is casual, but be prepared to dress for dinners (see Evening Dress below). The best approach is to bring clothes that can be layered: more layers for cooler, windier weather, fewer layers for warm, dry days.
Be sure to also bring:
Evening Dress
Evening dress falls into two distinct categories: Dressy attire or smart casual. Most evenings, smart casual is appropriate and can be defined as slacks and sports shirts or sweater for men and a skirt or trousers and sweater or blouse for women. Shorts, flip-flops, swimwear, distressed jeans and men's tank tops are best left to daytime and the poolside.
Dressy Nights evoke the grand traditions of cruising as guests dress to impress for special events on board, including a five-course gourmet dinner in the Dining Room. Jacket and tie are appropriate for gentlemen, while ladies wear a cocktail dress or gown. On Grand Voyages, many gentlemen choose formal attire.
The number of Dressy Nights on your cruise depends upon the duration of the voyage. The number of Dressy Nights for collector voyages is based upon the duration of each individual voyage of the ship.
Exercise Clothes
If you're a fitness fan or just like to stroll around the decks be sure to pack your exercise clothes. There are aerobics classes on the ships, treadmills, exercise bikes and other equipment in the fitness center on board each ship. The free Passport to Fitness program has the added fun of a reward at the end of the cruise for participating in onboard activities. Be sure to bring your running or aerobics shoes, swimsuit and a cover-up (for lounging, if not for warming up).
Items You Probably Won't Need
Bulky or winter-weight sweaters or jackets.
Rain boots and long underwear (outfitters throughout Alaska provide special gear needed for their activities, such as warm "moon boots" for walking on glaciers, waterproof rainwear, boots and life vests for river rafting or sea kayaking).
Don't Forget To Take
Laundry Service
Holland America Line has laundry service, dry cleaning and pressing service on all ships.
