Agree on the passport, apparently it's not a good idea to use it as a notepad and for writing down phone numbers in the back…had a heck of a time going through customs one time. Also, don't use a passport holder, they hate those things. Try to act like you've been there before, just use a wallet and keep your passport in a pocket on your suitcase. That works for most, if you like to travel frequently in and out of the country on days off, you will kick yourself real quick if your a keep your passport in your flight bag kind of guy. If I'm going anywhere, so is my suitcase. So, I just keep the must have things always in my suitcase. Good luck and enjoy the ride!!!
