It is one of my most favorite times of year to visit DC & highly recommend to anyone to find a time in your life to get to DC during this time of year.
2. The best time to visit is during the week due to the large crowds. But with three little kids & busy schedules, we had no choice but to visit on the weekend.
3. I recommend taking the Metro in. Unless you are staying right in downtown DC, the Metro is a super easy option. My husband always likes to drive in, but I voted for the Metro & it was a great idea.
