Looks like you got a pretty good deal. You can go get a portable usb 320 GIG hard drive at wally world or BB to ensure you have plenty of storage. I think they are only around 50 or 60 bucks. That would ensure you have plenty of space for a couple of programs and a bunch of photos if you don't have time to download. It would also give you a place for backups of your photos.

Sounds like its gonna be a great trip, be safe and don't forget your DTR buddies. Post up some photos if you can!!!
