Not sure which thread this was on but someone mentioned booking a place in fairfax. Fairfax is 20-30 minutes from DAR. I would check mapquest or google maps for a closer place to stay.
The map for the area has alot of places to eat, drink and oh yeah see the monument, lincoln memorial, white house. You could probably stay at the college 5 blocks away...
There is a lot of places around the venue to check out.
I am not sure of what time we can get down there, I am over an hour from there without traffic and the person going with me just had a baby 4 days ago.
If we can get down there early, we might just check out a local bar for some drinks and apps before the show.
My wife is going wednesday night, so I will be in rare form tuesday.
night with the wife and 3 kids... $50
night with the wife and no kids...$100
night away from my wife and 3 kids, with my friend, at a smashing pumpkins show ....priceless
