I actually read this on Fstoppers and damn it works. Thus I decided to share it. I have made a few annotations which I employ.
I take a portable hard drive, WD passport(1T), and a card reader. Both are virtually no weight and small. I go to the business center of the hotel and use their computer. The computer will either have a SD Card slot or not. If it does you don’t need your card reader. If it doesn’t here’s where the card reader comes in. The computer will most likely have an USB port. The card reader has an USB port. Plug it in and also plug in via the HD to the other USB port. Download your photos to the HD. You’re done, no internet or your own computer required. This can also be done at an internet cafe. To be sure get yourself an USB hub just in case the hotel or internet cafe’s computer only has one USB port. his works.
