I was on the Volendam in June to Alaska and thought she was a really nice ship. The artwork and decorations are beautiful, and the cabins are nice and large,with lots of storage space. You will love the ship. If you want to have dinner in the Marco Polo, book your reservation in person as soon as possible the first day on ship. We liked our tablemates so well we never did get to the Marco Polo, cause it felt like we were deserting them! The dining room was nice and most of the food was excellent, a few items could have been better, but considering how many meals they make in a day, some thing may not be perfect. Hey, at my house 2 out of 3 meals might not be great!
I will definitely book another trip on her, she is a great ship! Have fun!
