I am working with Best Bridal at the Ocean Crystal Chapel, but we hired our own Photographer and Cinematographer. I would not take a package under any circumstances where I couldn't: A. Know the name of the vendor they want to contract to photograph the wedding and B. Choose whichever vendor I wanted from a list they had!
We are using Rachel Robertson and her pictures are just stunning! She really has a knack for capturing the emotion of a wedding, not just creative pictures (which she does equally well). We met her last summer and immediately she felt like an old friend. I know my daughter (who's uncomfortable being the center of attention) and her rather shy fiance will feel very comfortable with her. Your pictures are the only thing that provides lasting memories and let's you see things you actually missed at your own wedding! Don't trust it to someone you don't know or haven't seen work from. What a stupid policy they have!
Good luck! By the way, Rachel's site is: www.rachelrobertson.com in case you're interested.
