I'm going to the Washington, DC area in 2 weeks. I'll be staying at the Crystal City Marriot (Crystal City Hotels | Hotels in Crystal City | Marriott Crystal City) and my training class is just a few blocks away. Is there anything within walking distance of my hotel that is a must-see? Any local restaurants that deserve my patronage?
I won't have much time to sightsee if I follow the training schedule precisely. They've even planned my dinners and "free time"! Dudes, it's not "free time" if you've planned it for me! But I hope to sneak out and see some things on my own.
Any advice for that area, or navigating Reagan National Airport, or travel in general are much appreciated. (I could especially use a primer on packing toiletries for air travel. I haven't been on a plane since the restrictions on bottle size were implemented.)
