I am in DC now & had some tips.
1. If you have contacted your state congressman to do the White House tour, I just did this yesterday. They tell you not to bring drinks into the WH. True, but what they don't tell you is that you will stand in the blazing sun for up to 2 hours once you get there & you can CERTAINLY drink your water while you wait (although there are no bathrooms.) It is a self guided tour, 6 rooms (looking in) Everyone in our time slot (hundreds) stood there with no water & it was pretty miserable. If there was minimal wait I would do it again. With that wait, not worth it to me.
2 I see lots of mixed reviews about Founding Fathers. Had dinner there tonight. Pretty good price point for DC, good food, and very large servings. I had the rotisserie chicken. It was 1/2 chicken with potatoes and green beans. Enough for 2! Had a good Man Tai, one was enough!! I thought it was a good place, though LOUD!! I would return.
Just wanted to put in my 2 cents!
