My team went to the DC regional in 09 and 10.

We stayed at a different hotel each year, but both were in the city, within walking distance of the Convention Center.

In 09 we stayed at the Four Points Sheraton, and in 10 we stayed at the Holiday Inn.

I found both to work very well for our team (about 35 people went each year). Typically, the rooms we stayed in had 2 beds, and we had 4 students in each. Each morning our team would meet in the lobby and then walk a few blocks (not sure of the exact distance) to the convention center.

However, since we aren't local to DC (from Connecticut), we took a train to DC the day before the regional, and one of our mentors followed us down by car with our tools and parts, and then just dropped those off at the Convention Center. That way, we didn't have to carry anything back and forth. After the regional was over, the truck came back and picked up our tools and drove back with us.
