Mmmmm... Quite a dilemma... If you have someone you can put on table guard duty, you could leave them out with the guests. Or maybe you could get someone to kitty-sit for the night (Oh Jeeeeeeeeeen!) or board them.

Other than that, I'd have to suggest splitting them among the various rooms. If Harry and Abby haven't figured out the door opening trick yet, put them and Flutter and any other kitten fosters around in your room. Then let Pouncer and Allen chill in the front room.
