Go to the website cruiselineformal.com for all the info you need for any cruiseline. It's pretty reasonable for a tux w/2 shirts. Beats schlepping a suit in your suitcase. My husband & cousins are doing this for our trip to Hawaii next year.
Ditto...I just used them for our Millennium cruise, being a large guy, i was a tad worried about sizing....but they did great! The price was less than I could get local, and I didn't have to worry about toting it around. Our cabin attendant brought it in before our first formal night and picked it up after our last....perfect.
