Our Alaska cruise on the Westerdam was fantastic. We had 3 generations, with teenagers being the youngest of the group, so I was a bit nervous hearing about the usual demographics of Holland America cruisers. To my pleasant surprise: there were many multi-generational families, and we rather enjoyed not having the ship overrun with small, running, loud children.
Rooms: we all had a row of balcony rooms, on the port side, which was perfect when we were in Glacier Bay. Our steward opened up the dividers so we basically had our own loooong balcony to share during our trip.
Service in all areas was outstanding. From our smiling steward to each restaurant server to the entertainment - ALL were so eager and friendly and we enjoyed seeing them in port having a good time with us passengers.
Food was amazing. We enjoyed the various restaurant choices, and there were plenty of options to choose from, including 1 member who is gluten-free.
Entertainment: the older grandparents really enjoyed the nightly shows and educational presentations in the main ballroom, while us parents with 20 somethings tended to go to the lively BB King's or piano bar or casino every night. Westerdam provided the right amount of partying, because we usually woke up early the next day for excursions, so we didn't need loud, late conga lines every night.
Excursions: so many to choose from and here's a brief review:
5 star for: Zipline in Ketchikan, & Glacier View Sea Kayaking in Juneau
4 star for: Halibut Fishing in Ketchikan (they caught Lingcod but not Halibut).
3 Star for Skagway Hike and Float trip (only because we are experienced hikers so wanted a more strenuous hike and longer time on the river)
Overall: I'd say Holland America is a bit more sophisticated for the discerning customer, which we prefer. We met other cruisers from around the world, and we all were impressed with Holland America!
