I had problems with my iPod on the last trip and brought only the usb connection and when I enquired and even has a look known of the computers the passengers could access had those ports fitted I spoke to a nice lady in the library whose computer had a usb socket and problem solved. Might vary from cruise line to cruise line though.
to charge an ipod without usb id recommend a cambridge audio ipod dock, charges your ipod,remote and has a connection for speakers. small lightweight and costs around ten pounds at richer sounds.
Thanks for this but have an adaptor now so no need for the usb option.
I doubt it...most ships restrict access to just the monitor, keyboard and mouse with the main pc hidden away securely. if its to back up or free your camera memory then most offer a service in their photo shops but this is charged at a premium and cheaper to do in port.
