Memory card backup
I have never found a Carnival ship internet cafe with this capability. I did take my laptop on our Med cruise in May for this purpose and for staying connected to family and work because we were gone for 3 weeks. I will NOT do that again. It was too heavy to carry through the airports and ship terminals and we were always leary of leaving our seats at the same time, in case someone stole it. We had to hide it in the cabin, not an easy thing to do!
I feel the same way about backing up pics on a disc, but I just watch the sale ads and purchase several cards before we leave and burn them when I get home. You can usually find an internet cafe or photo shop/booth in port where you can download the cards to a disc if you really want to do that though.
