I have heard that renting a tuxedo on board for a formal night if "relatively inexpensive."
Folks often have differing perspectives as to the defintion of "inexpensive." Please comment on approximately how much one would expect to spend.
I found the price on the Carnival website....I can't remember exactly how much it was - I looked around 4 months ago...I think it was like$70 or something like that. If you want the exact price, I found it on the Carnival site - go to the Bon Voyage gift section and it's there under formal wear or something like that. Hope you can find it.
