It was an awesome trip
  1. #1: A ROLLING backpack
  2. Comfortable shoes
  3. A luggage lock and larger lock (if staying in hostels)
  4. A credit card with no foreign transaction fees
  5. Packing cubes, packing cubes, and packing cubes
  6. Extra room in your bag for souvenirs
  7. A travel blanket.. Brrrrr
    Also suggested: blow up neck pillow, eye mask, and Dramamine
  8. Use your coins first!! You can't exchange these back to US $
  9. Cell phone data plan.. It's worth it
