Pick up one of those America Online CDs from a local Staples, Office Depot, etc., and use their complimentary hours.
One thing to beware of is when you return from your vacation, cancel the account (You'll have to give them a credit card number when you first sign up). their reps are trained/required/forced to keep you as a subscribing customer. You just have to be firm from the start of your conversation with them...don't listen to the BS line of questions and challenges they'll give you.
