Question: What ID, other than our passport should we bring?
Answer: Your passport is perfect ID. PLEASE lock your passport in your room’s safe. I take a photo of my passport and carry it in my phone. That’s for duty free forms and quick ID if we’re out & about. I also take a photo of my credit cards (front & back), and my Drivers License. In the past, I’ve carried photo copies, which also works. It’s a good idea to give the info or put the info in a place that’s separate from your purse/wallet should that be lost or stolen. Also, before you leave the US, please know where you can access a copy of your birth certificate should you lose your passport and need an emergency passport from the US Embassy.
