We did host an all-day LotR marathon once, but our food wasn't nearly this good! It would be exorbitantly expensive to feed everyone all of this, but perhaps I could invite seven friends (or pairs of friends), and they could each bring one dish to share? Small portions, to keep it both affordable and fit-in-stomach? That would be COOL.
This would be the most fun ever.
I went to a party like that once, and we watched all three movies over the course of a full day. And ATE.
