The absolute first step in planning any kind of overseas adventure is to have a passport! Having a grand itinerary planned is pointless if you aren’t able to actually make the journey. Without this little blue book, traveling anywhere outside of the United States is mostly impossible. Even if you don’t have immediate plans to travel, having a passport handy is great to jump on those last minute deals and to have a second form of identification any time you are handling official business. Plus, regular adult passports last 10 years, so you have plenty of time to put some stamps in it!
