Fancy a few days in Washington at some point and we'd heard good things about the MCM. Someone described it as a wall off noise going round. Perhaps the weather meant it wasn't the case for you.
Time wise, not being fast isn't an issue. I run with my wife and we get round in about 5 hours (not that I'm much faster with out her lol). We did Barcelona this year, which was great, but not many runners around the 5 hour mark or support for them.
