Some things I make sure I pack are my Laptop and my iPhone. Not only do I take the iPhone for the phone, but many Marriott Hotels have a place to plug in your iPhone/iPod to listen to the music you like. I wish all of them did, and that they made sure they were compatible with the iPhone and not just the iPod Touch. Along another travel packing line, I have started carrying a small digital travel scale to make sure my bags stay under 50 lbs. Nothing like being surprised at the airport.
