The couple makes the romance, not the location. Not that I would recommend that you spend your honeymoon in Gary, Ind.

I would pick NYC, but then I lived in the DC for 15 years.

As for hotels, I'm only going to suggest that you avoid the Waldorf. Went there for an anniversary, and it was really disappointing. Room was rundown (peeling wallpaper, not entirely clean), but what I was really surprised with was the lack of customer service. The best part of the hotel is the lobby.
