I have 4 kids(11,9,7, and 1) and wife traveling to d.c. this week...we will need to take the metro from DCA to Chevy chase MD to our hotel about 10 am in the morning(5:30am when going back to the airport)..we will have two rolling bags and a stroller. we will need to change to a different line at the metro center to get to our destination..would you feel comfortable doing this?? should we just rent a car? thanks for the info
