I sailed the Ryndam to Alaska on 8-27 this year. We sailed until 9-3. I had read those reviews as well and I called Holland America directly. They told me that was an isolated incident. We had no problems on our cruise and no one got sick. The best thing you can do to present getting sick is use the Purell hand sanitation stations on the ship everyone you eat, go to the bathroom, etc. My travel agent also called. My mom is 77-years old and is on oxygen all the time due to lung problems and a history of 2 very bad heart attacks. The crew was there at every turn to help us with her wheelchair and taking her through food lines, getting her on and off the ship at ports, etc. We had a fantastic time without a stitch of trouble and I assure you that you will have a great time as well. If there are any other questions, you can email me at
