It will be a miracle if you can get an AP that quickly. I would come up with plan B. Also remember that Americans will need a passport if flying to Mexico, Canada and the Carribean to gain entry. You can still drive to Mexico or Canada without a passport until 2008. We're going down south for a little vacation and the quote below was with my airline tickets. "As of January 8, 2007, United States citizens are required to have a valid passport to enter or re-enter the USA via airline transportation. Visit http://www.travel.state.gov for information on how to obtain a passport, including forms, fees, and how to locate a passport acceptance facility near you." Whatever plans you'll make, have a nice and safe trip.
