Some have found it works to add a bowl or bag of ice in the chiller/cooler. Then again, when returning from a long excursion, the cooler was wide open and everything at room temperature. I have never heard of that happening before or since. Then again, again, our steward had a multitude of problems which even the head housekeeper did not fix. That was on World Cruise #4 for us and the first time we have ever had anything but high praise for our stewards. We spent much time from Bali to London being frustrated and annoyed. Why would someone think we wanted only one drinking glass or no body wash or our stuff moved around??? Rant over. We leave in a month for another Viking cruise.
