A method I've use in the past was a cheap Android tablet (I bought this one new for £70, but you can probably get a more powerful one second hand a damn sight cheaper) with micro SD card slot and micro USB to usb cable to allow connection between my camera tablet.
I then downloaded a file explorer app (this was years ago, and can't remember its name off the top of my head, will check when i'm home) which allowed me to copy files from in this case my camera to the microSD card.
The advantages of this were I was able to check and chimp images on the fly, and send them off to people via email/to server/social media. Now with Adobe CC you can probably get some basic editing done to.
The risk I can see with the pi solution is the networking. You mention SSH, does that mean you'll have a laptop with you to? Also, presuming you won't have a screen, what will happen about connecting it and then finding it on the nework? There's also the risk of your accommodation blocking networking ports outside of http/https range.
