We JUST did this at the Polynesian at the beginning of September. We did the mini session for $150. For that price, you get 30 minutes of picture-taking and a flash drive with all the unedited photos and the license to print them. In our 30 minutes, we got over 130 photos. Our photographer didn't include any photos with eyes closed or the baby not looking. We got 130 GOOD photos.
We thought it was worth it and would do it again. We used this as our chance to take pictures for our 1-year-old. We would have spent that much, or more, at home, so for us it seemed reasonable. The quality of the pictures is great, and there aren't many edits we would want. Our photographer told us that if there is one we want edited, we just needed to call. I'm sure there would be a fee, but he said Fine Art Photography would help us out. We don't think any need editing, at least nothing beyond what we can do here at home.
They asked what we wanted when we made the appointment, and our photographer arrived early and knew exactly where to take us for what our desires were. We got a few of just the baby, a few of my husband and myself, a few of us individually with the baby, and lots of our family of 3. We brought a Mickey cupcake to the session and he helped us do the "smash cake" series on the beach with the castle in the background.
Like I said, we were very pleased and thought it was worth it. We put a few of the photos in our trip video (link
here). The photos start at 18:18 if you want to see what they look like. I'd be happy to answer more questions if I can.
Also, we don't do PP or PP+, so I have no idea about the inclusion in those programs. And to answer your question about your own photos, you probably can take nice shots yourself, but you won't have any of your entire family, your photographer knows what areas are best, he can clear the space, etc.
