I just finished a cruise and had the USB photo package. If you go to the photo gallery after you board then they give you a code which allows you to download the photos whilst you are on the ship at photos.rccl.com on your own device. I think you need voom. The photos were updated each morning. Alternatively you enter your email address and you can then download them for a month after your cruise. They didn’t offer me a USB stick. Was very happy with the way they ran it and photos were all amazing.
