DC Dopers! Help me plan a romantic New Year's

My ex-girlfriend is coming to visit me in DC from Dec. 28-Jan. 2. We’re pretty much already decided there’s no way we can be “just friends” during this trip, since we broke up because of distance and not anything else. So, I’d really like to turn those few days into a fun, romantic time. I’ve been wondering…

Where’s the best place to be at midnight? Is there something on the Mall every year? Is there a better alternative? (Please do not let the possibility of terrorist threats exclude any ideas.)

I hear there’s ice skating somewhere on the Mall too (perhaps the Ellipse). Is that true?

What are some other, general winter/Christmas-time things that would make for a good time?

I don’t expect tons of replies, given the narrow demographic, but some advice would be great. I really want to make this one count.
