Hey, I can hijack a current post in an on-topic way

Thinking about stopping over in DC for the weekend between Christmas and New Year's.

I have no idea what's in DC, so rather than the OP, we're looking for a top few list of the obvious things to see - that big statue of Abe Lincoln in his chair, that sort of thing.

Also, where is the best place to stay (area or hotel) and does anyone know if that weekend will be a good one to pop my cherry on Priceline, or will the hotels have good rates anyway ?

thanks in advance
Stewie
