Going on a 12 day cruise vacation with one carry-on luggage is certainly possible, but it requires careful planning and consideration of what is necessary and what is not. Here are some tips on how to pack efficiently for a cruise vacation:  Start by making a list of the essentials you need to pack including clothing, toiletries, and electronics. Choose versatile clothing items that can be mixed and matched, such as tops and bottoms in neutral colors. Bring lightweight, wrinkle-free clothing that is easy to pack tightly, like a few dresses that can be dressed up or down, and clothes made from quick-dry fabrics. Opt for shoes that can serve multiple purposes, like comfortable walking shoes or sandals that can be worn during the day and simple dress shoes for when you need to dress up a bit in the evenings. Pack toiletries in travel-sized containers, or buy them once you arrive at your destination. Bring a foldable tote bag or backpack for excursions or beach days. Make use of the ship's laundry services by packing fewer clothes and washing them as needed. Finally, it's important to check with the cruise line regarding their specific luggage requirements and restrictions, some ships may have size and weight limits for carry-on luggage.
