oooooh... no copy??
When I'm on vacation, I almost religiously copy my photos to my laptop as a backup... My dad had a horrible experience on my parent's trip to Australia earlier this year... he was using relatives computers to copy his pics from his camera storage to a Sony flash drive... and the drive crapped out with 2/3 of their pictures on it... and he had already wiped them from the camera's memory card.
Now SD cards are so cheap, I'd just get multiples and leave all my pictures on them, and make duplicates to the laptop.
