Here's what is likely to develop as this builds. There will be a list generated of people who say they're coming. Many will want room mates. I'm certain there will be several blocks of rooms at several hotels. There is likely to be a list of people seeking roommates to share the cost. There is ALWAYS tons of communication on these types of functions. The DC Chapter is always on top of things and they will have it together. You can start looking for hotels yourself too, remember there will be LOTS of people coming for the Inauguration. Freepers share with each other well. Roommates match up by sex, gender and smoking and drinking habits.
