Okay, here's my update! I am home and logged onto disneyphotopass.com. Everything is totally normal. All of my pictures are there. I can add borders and crop and all of that good stuff.
Will be ordering the CD in the next couple of days, and I'll post back only if there are problems. Otherwise, it's all good.
I saw just as many photographers as normal, which is nice. As for the ride photos, you just take your lanyard up to the counter and tell them your photo number, and they add it to the card. Super easy!
My one caution--when they punched my card, they only punched it for five days instead of 14 or whatever. It wasn't a problem for us, since it was punched for the day after we left. But definitely double check!
