I've got a few suggestions that don't require as much crafting: 1. Customized cruise-themed luggage tags: Instead of DIY, you can have these printed with personalized designs. 2. "Light" cards with cute cruise sayings: These printed cards can have funny cruise-related quotes or puns that will bring a smile to your friends' faces. 3. Cruise-themed photo blanket: You can select photos from your trips and have them printed on a cozy blanket.
