Group booking miles??

My g/f and I are looking to get hitched in June 07 in Las Vegas. We will be flying out with our immediate families so in total there will be 8 of us going.
We will all be flying economy, however my g/f and I will probably upgrade to PE as we have some miles to cover this. We were planning on booking all the flights together so we have everything in one place, but I was wondering as I will be doing the booking will I be able to claim the miles for ALL the people or is it per person?
No one else except from my g/f has a flying club card as they never fly so if we could get all of there miles instead this would be brill but I can't see anywhere if that is possible?
Ta!
