I would like to know this, as well. I posted a thread related to this a few weeks ago but didn't get any response.
I know that they can provide a Disney photographer for a wedding according to the book I read on weddings when we were waiting to get into Shutters. I would hope you could get a Disney photography session like at WDW but all I saw was the wedding advertisements-where they would make a lot more $ than just the $275 for the hour sitdown-who knows.
Maybe someone will know.
