If any of you guys going to MACNA are planning to go see the monuments and museums, here's a suggestion, get a car service for like 4 hours. I grew up near DC and have been there many a times taking visiting relatives. DC in the end of summer is freakin hot and crazy humid. Everything in DC is spaced out kind of far so you're constantly walking. A car service is perfect because they'll drop you off in front of everything and will wait for you there until you're done site seeing each thing, plus you can have them blast the AC while you're in the car resting going to the next monument!
It runs about couple hundred for 4 hours, but definitely worth it in my opinion. You will see a lot more in a shorter amount of time, don't have to worry about finding parking (it's not like SoCal where there's valet everywhere), and won't get turned around on DC's crazy streets (fun fact: when DC streets where getting planned out, the planners purposefully made the street system confusing because if we were ever invaded, they wanted to make it hard for the invaders with their tanks and vehicles to find their way to the Whitehouse and government buildings. Well, they succeeded!)
