When I was in the front of Hollywood Studios, I found a sweetheart of a photopass photographer who took several magic shots with me. It wasn't busy which I think was why she could do it. I don't know if the shots are available anymore since this was a few years ago.
In MK back by the wall near BOG, there was a photopass photographer who took a magic shot of me and closer to Ariels ride was one who could do magic shots too. Both were only there in the morning I noticed.
A friend of mine told me there was a photopass photographer on the bridge between the hub and tomorrowland who could do a magic shot or two but I've never seen anyone there - I think my timing was off.
And on main street in MK - many of the photographers can do a magic shot.
In Epcot back in World Showcase, I've come across one who could do a photopass magic shot but they were only there for a few hours early in the day (between 11am and 2pm was when I saw her). I don't know if anyone will be there during F&W Festival since it gets so crowded in World Showcase then.
In AK, the person without a tripod on the way to the Tree of Life did a magic shot of me in April 2015 that I like. And the main walkway in the back of the park between Asia and Africa, there was a photopass person without a tripod doing a magic shot too.
Basically I'd ask any photopass photographer without a tripod if they can do them. They are fun. I'm purposely not saying what the magic shots were so you can be surprised if you get them.
