Okay, I'm a real newbie. I have never been on a cruise and I have never been to Alaska. I am going on the Princess Dawn 12 day cruise leaving May 30th. I am almost more nervous about the "dress" aspect of the cruise than anything else. It appears, from the literature, that there are formal nights (are they mandatory?) and casual dress days. I keep wondering about how large a suitcase and how many suitcases I'll have to pack to bring so much "dressy" wear....as well as comfortable clothes. And I am concerned about how you transport so much luggage about when doing the land tour portion of the tour. I am really looking forward to much of the cruise...most especially the nature and wildlife viewing. But I really must admit that my idea of a good, relaxing vacation isn't spending much time in formal wear, nylons, heels, etc. Can someone give me some personal insight into this problem?
