I took a lot of my own photos, so the photo pass shots ended up being a lot of Wonderful Hubby and me in front of Disney object/background pictures. If you spread them out through your trip album, they help you keep track of what park you are in. If it's all you get for photos, it can become rather boring. I was also surprised by how often I'd want to use my photo pass for a ride photo and couldn't do it. I wish they'd add that capability to more of the rides.
That said, I'm really glad I got the photo pass CD at the pre-purchase discount. It's almost impossible to get a good picture of yourself, and the photo pass photographers took that headache completely away.
