Rule no. 1: Wear sunscreen.
Rule no. 2: Wear a hat.
Rule no. 3: Take the Metro. Buy a SmartCard. Yes it seems very safe, people are very nice and it is fairly clean. Much cheaper and more flexible than a tour bus.
Rule no. 4. Make sure your camera battery and phone battery are charged each day. I must have taken a thousand photos, I kid you not!
Rule no. 5. Realize you will be doing the tourist thing all day long. It is tiring, but oh so worth it. It also means eating out a lot!
Rule no. 6. Because you will be at it all day long, make sure to wear comfortable clothes and shoes. Also bring bottles of water with you. I cannot emphasize this last enough. Very easy to get dehydrated.
With that being said, we are leaving DC tomorrow and heading to Williamsburg. I haven’t been there since I was 10 and I am so excited.
