Our cruise was a great experience.
Seattle was a breeze embarking. Took 20 minutes from arrival at terminal until being in our room
The ship is a good one. Up to Holland standards in every respect. Our suite was spacious and comfortable, and our concierge was professional in every respect.
The passengers were a mix of ages, but generally skewed older. 65 plus. There were a few families with children but were never an issue as far as noise or behaviour was concerned, as well as some younger couples.
The venue is terrific. Cruising the inside passage is a sight to behold as was most of the trip. Amazing scenery and natural wonders.
The only negative for me was the first couple of stops,Ketchikan and Juneau were also stops for several other cruise lines on 7 day passages,so the ports were clogged with 4 or five other ships docked at the same time,making walking through town a battle of will to get anywhere. As the ship went further north, there were fewer other ships at port. The Amsterdam is the ONLY cruise ship that docks in Anchorage.
The Captain and officers were efficient and professional, but NOT a chatty gregarious bunch, but the did their job and they're not paid to be entertainers.
Regarding shore excursions, be aware Alaska is NOT cheap when it comes to most anything and excursions reflect that fact.
We booked excursions the day before or not at all depending on weather conditions and costs.
The weather was changeable throughout the trip. We had several glorious sunny days,and some cloudy cool days,but little or no sustained rainy days.
Dress in layers. You can always take things off, but if you under dress and the wind or rain comes up, your out of luck.
Trying to describe the scenery and wildlife via words or pictures is beyond my abilities as a writer. Sufficient to say you will be constantly in awe of what you see every day.
