I will be spending a week in DC in a few weeks and am trying to pick a property at which to stay. I will have business downtown near Foggy Bottom 2 days of the week and out in Arlington 1 day while the rest I'll be free to spend with my family (wife & 5yo). I can take the Metro to everywhere I need to go, so I'm more concerned about a place that is convenient for my wife and daughter while I'm not around as long as it's near a Metro stop.
Fed Rate is the same for pretty much all of the properties, but varies a little in what you get for the price i.e. Washington Marriott it will get you Concierge Level, whereas others don't. I'm Gold so I should get lounge access anyway.
I'm thinking about the Crystal Gateway Marriott, but I wanted to solicit other suggestions and opinions.
