Just returned last week. There were quite a good number of photographers, and most were standing around with nothing to do. We got a good number of pictures, some really cool magic shots in SWGE. Lines were pretty short if there was any line for the photographers (in front of the castle, for example). I never saw a photographer taking photos in Carsland on the road, like they normally are. They did have one in front of the Carsland sign, like usual.
For the person with 2 tickets, I am not sure how it is linked. I would recommend you go to one of the two camera shops and have them load the Photopass one week onto the app with you to be safe. That is what I did. You can go ahead and put the ride photos and such on the app before you have purchased the Photopass, and they will be watermarked until you have the photopass added.
