Sorry this has no particular order, but I thank those who reviewed before me and wanted to contribute.
We really enjoyed our cruise on the Westerdam. You have to realize that it is an Alaska cruise and what the clientèle will be... i.e. a mix of old people and families... not too many young 21+ people, but we still had a great time. Next time, we are going to try and do a Caribbean cruise with a minimum age to try and avoid the children. But that's just because we're in our late 20's/mid 30's without kids. For example, it was totally impossible to get in the hot tub... that would have been nice, but it closed at 10. And sitting anywhere near the pool got you splashed and listening to "Marco Polo" for hours on end.
The buffet was great, but after we discovered the Vista dining room we never went back. The food was absolutely incredible there. We had open seating... some classier people I think had reserved times and tables, but honestly we enjoyed the flexibility to go whenever we wanted to, and never waited very long in line. I never dreamed the food would be this good, and you could order as much as you wanted.
Small room, no window, just enough space for two but no more. But then again, why sit in the room?
