Agree with staying in one hotel, Hyatt Reston being one of my faves for upscale, tons of options for more reasonable prices. If you're headed downtown during rush hour, though, I would definitely leave yourself more than an hour to get there. Rush hour in DC is manageable if you know backroads, but if you're not overly familiar, the main arteries can be maddening.
