1. what to pack? will it be sweater weather or colder?
Depends on where you’re from since the average temperature for Aug is 60-67°. I’m still wearing shorts then during the daytime, but you might be very cold. So to save space in your suitcase optimize your top layers.
A) Bring your largest most spacious, water friendly, outerwear and layer underneath. Pick up an oversized coat (new or used) for the largest person and pass their current coat to the next person smaller and so on. Give the oversized coat to a charity in the fall.
B) go to the dollar store and pick yourself up the plastic raincoats. Even waterproof coats get soaked in a downpour.
C) plastic bags from a loaf of bread offer great protection inside shoes with a larger rubber band during downpours on an adventure. For smaller feet you could consider doggy do-do bags. Purchase the larger rubber bands also.
D) sweaters need a shirt underneath, consider the sweater clean and reuse it. Most others on the ship will be doing the same thing. A fleece can be worn like a sweater.
E) Formal night: Wear a sweater with collar shirt, dress pants, maybe with a tie. So think cottage Christmas by the fire looks. Your pictures will be lovely then. I would leave the dresses at home it’s not worth the extra shoes in the heavy tight suitcase. Alaska cruises are the least formal of any cruise Disney has, Transatlantic and holiday are the most formal.
F) Consider a water resistant hat that will keep rain off you neck and away from eyes/face. Styles will vary but function will make you more comfortable to enjoy your site. Or use a baseball cap under a water repellent hood.
G) buy several water repellent sprays on
Amazon use it for shoes and hats. All adventures will go on rain or shine. Spray the shoes at home and bring 2 cans in the suitcase for your weather needs. Like the front of pant legs the back usually is dry.
H) bring looser pants that you can layer leggings under. Gentleman might prefer longjohns or a thin pair of longer shorts. This is only for individuals who are cold very easily most won’t need this.
2. Other things you found worthwhile to bring?
Some like binoculars. Big suitcase for the kids too.
3. Other than seeing incredible sights what do you do?
Whale watching is best in Alaska.
4. Will the northern lights be visible?
Never say never, but I didn’t see them on our trip.
5. I had back surgery in June, will there be a lot of walking? lot of stairs?
This can be a problem. We went on the Bering sea cruise, and it was wonderful. The Disney personnel who took us to the Bering sea ship, walked us there so fast my father couldn’t keep up. And he was totally embarrassed, the host knew that we would have difficulty because she knew we needed the elevator. Read the descriptions carefully on the adventures, and believe what it says.
Sidenote: bring your old shoes that you can throw away to give your self space in the suitcase for souvenirs. The same can be said for old unloved shirts or jeans. I have a bag of stained/ill-fitting clothes and old shoes just for traveling. If goodwill is going to throw them away I might as well do it myself.
