Hi Cruiselover. We'll be on the Dawn Princess soon, cruising Alaska. Our TA told us that a sportjacket and tie is all we need for the "formal" and "semi-formal" nites. That's all I'm packing. This is a vacation, not a formal ball or wedding. I think that if Princess expects a tux (or even a "dark" suit) they need to clean up their own act with superior food, drink and entertainment. To expect us to go all out while they're cutting corners is absurd, especially at the price they charge for a cruise. I'm gonna be comfortable!
