I'm so sorry you're having such a rough time finding Photopass photographers! DH and I saw a lot of them when we were there in Feburary, but they all seemed to be in really bad spots.
(i.e. the picture we got in front of the castle - it's at such a bad location and angle, DH practically covers the entire castle!!)
I hope you have a lot better luck with them soon! I'm sure you'll end up with some great family pics!
