Arriving in Dulles on Friday June 17 around 8 PM. Planning to do sightseeing on Saturday. probably use one of the city tours. Leaving on Sunday at 7 PM from Dulles. Does it make sense to stay near the airport and go into the city on Saturday or will it be better to stay in the city ? How easy is it to get into the city from Dulles with a toddler in my arms ?
