My parents (both in 60s) are stopping over in Wasington Dulles airport for a 10 hour layover, they arrive in at noon and depart at 10pm for international flight out.
What should they do or see, without them having to rush too bad back for flight out? Would it safe to say they need to be back by 7.30pm, and would they get stuck in traffic on way back?
I thought they should just walk around Georgetown? but they think "how do you go to DC and not see White House.etc"?
Any ideas or thoughts or good tours would be appreciated.
Keeping in mind they going to be tired after a 11 hour flight to get there.
