- Book airline tickets (Duh!).
 - Organise your ESTA (Electronic System for Travel Authorization).
 - Hire a car.
 - Pre-book accommodation, not really necessary if you are travelling across multiple states. From my last trip motels are plentiful and we had no issues finding a room.
 - Get a travel SIM for your phone (not essential).
 - Get a travel card that you can load up with USD, shop around though the options and fess vary greatly.
 - Read lots of reviews on the places you want to visit.
 - Do an itinerary – have at least a rough plan of what you want to see during your stay.
