This is a wonderful landmark to see. Our guide took us there and ensured that we had necessary tickets to do the tour. Once you get past that, you can explore most of the grounds on your own at your leisure. The restaurant and restroom facilities there are well suited to accommodate people of all ages.
Vastly over priced to hitch a ride to Mt Vernon and a 4 break on the 18 entrance fee and a drive through Alexandria, Get to Mt Vernon yourself - Mt Vernon really worth it, but not worth paying 78 per person
Apart from just driving from DC, there was no other service . Not recommended at all.
