We are going on a cruise in June (my first), so I'm finding this post interesting!
We are taking ALL the medications... just in case (we have multiple health issues) including strong painkillers as well as paracetamol, travel sickness pills, Immodium AND Dulcolax. Sunscreen. A hot water bottle for my back. A small hand held steamer to get the creases out of our clothes. My kindle. A small feather cushion because I hate non-feather pillows. Magnetic hooks. Big clothes pegs so we can dry swimming costumes. The only sweeteners I like, and the only decaf instant coffee I like, for our cabin. Small rechargeable hot brush for my hair.
The cruise we are going on has a craft room - I'm going to find out a bit more about it and maybe take some small crafting bits with me if everything isn't provided and they do things I am interested in.
DH may well take a camera. Both of our phones take good photos but he does like his camera.
Clothes, including for the formal nights, shoes, toiletries, passports, debit cards, chargers etc. of course. The cruise is all inclusive with tips already included so no cash required.
