Havnt done the Arlington yet coz Crystal City has had the 2K bonuses + 1K for booking on-line... hehe. I will say, if a convention is at Crystal City, like last week when I was there, the best you'll get is one of their "larger" rooms. I've NEVER gotten a full suite, typically get one of the balcony rooms, which is comparable in size. It's 10 min to the airport in their shuttle... so thats convenient.
