On a recent cruise we had several theme nights:  A kimono night, a Dutch Night, Black & Gold Ball, Black & Silver Formal Night, Halloween Monster Mash Party, White Dinner Formal Night & Tropical Paradise Dinner.  I did dress up for many of these but with weight restrictions on airlines it is hard enough as it is to pack

.  I do feel though, that when you get into the spirit of things you do get more out of a cruise.  Would you go to the trouble of dressing up for themed events like Halloween on a cruise?  .
