La Madeleine would work, since it's easy to manage a large group and reasonably kid friendly, since I'm hoping certain people with children who I haven't yet met will bring them.

I'm thinking we'll call foo for 10 AM on Saturday, or so, the only problem is making sure that the cats have a safe, cool place to stay if we have to check out of the hotel.

LM in Rockville works though, as long as I can find a hotel reasonably close by. If I needed a phone contact for people who are non-LJ, would you be okay with that?
