That's what I thought we would do, but our photog (Sascha Gluck) had serious concerns about not being allowed on the property. Since we really wanted him as our photographer I decided to get something in writing about the outside vendor requirements, bite the bullet and just pay whatever we needed to have him. We're going pretty cheap for the rest of the wedding (i.e., dinner reservations instead of private reception) so it's worth it to us to spend the extra dough on good photos. Your photog may be okay with sneaking around... If it were totally up to me, that's what I'd try to do. Honestly, has anyone's photographer EVER been turned away on the wedding day? I'd be willing to bet no.
