Phone cords - You don't need a high quality one since you will probably lose it or leave it in the hotel all the time. Most any dollar store will probably have them.
Network Cable - There are some really good mini cables out there, I forget who had them (Xircom perhaps?) but they were incredibly thin.
Do a search on froogle.google.com for retractable ethernet cable

and a few will come up for as low as under $10 (J and R Music World) , phone ones under $5
