We did the Poly session in August 2010, 1st session of the day. I'm not sure if ours was "extended" but it was at least a 1/2 hour long. I am a hobbyist photographer so am probably more critical than the average client, and while we did get some OK pictures (and most importantly achieved our goal of a great family shot), the images were all over the map quality wise.
The main issue we encountered was inconsistency with exposure, some images were overexposed and others underexposed - even in the same location. We also had lens fog issues early on because the cameras were cold and outside was hot and until the cameras came up to temp the lens would haze over. Those 2 issues aside, our photographer was great, the kids really enjoyed her, and we got "the shot" we wanted, which was the sole purpose of our session. Would we do it again, absolutely! But it will be a few years.

Here's a link to some of the images, both good AND bad.

As for linking to your photopass card, no, we had to purchase that disc/rights separately. They gave us a CD of our images on the spot as well as several prints and the release. We also had a photopass card and they wouldn't add them to that, however we could upload them once home and add borders and order photo gifts, but the modified images wouldn't come saved on our photopass CD we ordered.
