Second cruise, second with HAL (Zuiderdam 2010), so I have little to compare to. I have a disabled spouse who walks but have only 50% use of left side, so I book tours etc. with this in mind.
Amsterdam - 14 day cruise June 29th to July 13th,2012. We did stay in Seattle for a few days before and stayed at the Inn at the Market, excellent little hotel.
The ship is quite nice and I like the feel of a smaller ship. I do like the decor of the Amsterdam over the Zuiderdam. But at the end of the day I'm all about the destination, not the ship or company. It was the itinerary that I wanted and almost cancelled this cruise at Christmas time as we already did Alaska (our first cruise).
Cabin 7056 is very small and noisy. You hear a lot of noise from the doors which are just outside your room as well as the staff hose down the deck (outside your window) every morning between 5 & 5:30. Personally I don't think it's suitable for two people.
