I don't think this would work. If you look at the falador party room world 103, it is chaos. Everyone is lagging and spamming, so at most (with 2 gigs of ram on low deatil) I could stay logged in for two minutes. And with the new countdown system, I would lag out before anything had even dropped. In adittion, the party will already have over 1000 people in it, so why encourage the other 1000 people to come as well? Then it would be world 103 all over again. The best solution would be someplace out of the way, but NOT a house. Houses are static and (at least in my own experiences with crowds at houses) seem less capable of handling lag than regular areas. Perhaps put it in a town out of the way like burthrope, where no one really just wanders there. That way everyone there it a tip-er and there can be as little lag as possible.
