Looking at flying into Washington DC from Uk stay 3 nights then fly to Nashville. 2 adults and ,1 18 and 1,16 year old. Have found that Southwest fly from Baltimore airport which is 35 miles. Have looked at transport links on TA and have decided to stay at "The Liason" Capitol Hill so near to Union station, apparently a 10 mins walk, and get to the airport that way.
My question is, would it work out cheaper, and easier, for the 4 of us and 4 cases to get a taxi or should we continue with our plan to use the train ?
Thanks in advance.
