Well, I hate to start with the bad news, but your photos from June of 2016 are likely long gone by now. I think they generally only keep them online for 2 or 3 months. If you've kept in contact with anyone else from your trip, you might see what they have.
How it works is that you go to
http://www.adventuresbydisneyphotos.com/ and put your code in. Over and over again, day after day, until the code is accepted, and you see a bunch of photos. You can download them individually, or download zip files of photos, or mark photos as your "favorites" and then download a zip file of your favorites.
I have only ever once received notice that the photos were out there. Just kept trying. *Usually* it takes a week or two, but it's been known to be faster, or much longer, just depends on where the adventure ends, where your Guides are going next, etc.
I'm sorry you never got your photos. You could *try* conctacting
ABD.Guest.Communications@AdventuresbyDisney.com. I wouldn't hold out much hope they still have your photos, but it never hurts to ask.
