This will be my first "cold weather cruise" and I am not sure what to expect and pack. We will be on the Caribbean Princess. If it is cold will they heat the pools and/or hot tubs? If it is raining will they close them? What about the outdoor movie nights? Is there a dome or cover to protect from rain or do they just cancel the shows? If it's not rainy but cold do they allow you to bring a blanket from stateroom? Also I have a question about anytime dining. We are a group of six, so will that likely make it more difficult to get a table together nightly? Will they break us up? When I tried to sign up for traditional dining, it said the 5:00 was full but the 7:15 had a wait list. If we do go with the 7:15 dining time, if there is room, do we need to let the waiter know ahead of time when we try the specialty restaurants, which we plan to do each of them. Thanks so much for any help!
