I have taken two "inside" passage cruises, one that left from Vancouver and one from Seattle...Both were totally different. It seems the one leaving from Seattle, at least to me, was anything but inside...The trip from Vancouver was breathtaking and it would be the only way I go, if I'm lucky enough to go again.
What ship are you cruising on and where does it depart from?
You get so much during the day, I wouldn't worry about what you miss at night, I'd tell you, but I couldn't see.....You are still fairly close to land during the night, but the views in the daylight are amazing...
Just got back for 7 day cruise from Seattle. West side (ocean side) of Vancouver Island was windy and rough as was our exit out of Skagway into open ocean. Crew taped "barf bags" on elevator entry points. We wil go out of Vancouver (city) next time. No you do not miss much at night. Find a cruise that includes the Tracy Arm.....that was amazing!
Well, yes, certainly you "miss" what you are traveling at night. BUT, you do have daylight cruising of northern Vancouver Island, and the Queen Charlottes during the northbound trip, and can have scenic sailing the entire day, going southbound. But, there is NO fixed routing or time, they can and do vary a great deal. I have been on cruises where they were all the way to Vancouver by 10pm, others, it's dark by Campbell River.
It is imperative, you do your homework. Every cruise is a compromise. Find out about routes, glaciers, ports. I frequently find, people having problems, and making "mistakes" with interior Alaska Travel. Make SURE, you want to "go" to Fairbanks, and know what is available how to spend your time.
