What mistakes do people make when packing for a cruise or resort vacation?

One of the mistakes that people make when they're going on a fun trip such as a cruise or a resort location is they forget to pack clothes for a more formal event. Such as, maybe the cruises will have a nice formal dinner so you'll need to have night time attire for that. Of if you want to go to a nice restaurant at the resort location you need to have something that will be appropriate for that restaurant. So they pack too many fun clothes and forget some of the formal clothes that they might need.
