I have sailed out of Baltimore several times in the winter without any problem. As already mentioned, the Baltimore port is smaller and much easier to navigate. The Vision is a smaller ship and very easy to find your way around. It will have fewer passengers and will not be as hectic as a larger ship. When the weather isn’t nice enough outside, the indoor pool is an option. Definitely take the longest cruise you can. It will be over before you know it. Enjoy.
