If you haven't made Valentine's Day plans yet, don't panic, but do look here. We've posted lists of D.C.'s most romantic places. We've compiled 10 date ideas for $20 or less, most of which don't require reservations. We've suggested dozens of Metro-accessible dates on one handy map.

Tell us about your favorite romantic date ideas -- maybe the view from the Kennedy Center's terrace? -- and you could win tickets to see Haim at U Street Music Hall on Valentine's Night. (Dominic Bracco II for The Washington Post)

And we're still giving you one more shot: During tomorrow's Got Plans? discussion, we're looking for your top last-minute date idea. Something spontaneous and romantic that tells your date how you feel about them without requiring a ton of forethought. (Not that we would ever encourage someone not to plan for Valentine's Day. Of course not.)

The best submission will win tickets to see Haim at U Street Music Hall on Thursday night. (Talk about last-minute date ideas!) The three 20-something sisters won the BBC's "Sound of 2013" competition, named the most promising act of the year by a vote of more than 200 critics and industry insiders. Their harmony-rich synthpop is smooth, infectious and perfect for a date night. Given that recent winners of the same contest include Adele and Ellie Goulding, it could be a chance to say you saw Haim way back when.
