My husband and I had only 2 full days in DC though. We had come from a night in NJ and 3 in Phili. We stayed off Dupont Circle with my cousin, her husband, and twins. Basically, since we had little time, Tuesday we had breakfast at Fire Hook, did a bus tour (I've been to DC but husband hadn't so this was an easy way to see a lot quickly). We also went to the Canadian embassy as husband misses home and he wanted to stand on Canadian soil, if only for a moment. But, as he says, "The Canadian government at it's finest, open only from 9-12'. So he couldn't go in but he lingered there. We also took the Metro up to Shaw and did some serious walking to find a veggie restaurant; which by the way, there is a great veggie soul food place up near Howard.
Anyway, on Wed. we spent the day at the Holocaust Museum after breakfast. We had lunch there and took our time. By then we were beat and were leaving the next day at 1 so simply walked to Whole Foods, grabbed food for the plane, and that was it.
BUT...thanks for extending the welcome. Next time
