the only thing I would suggest is when going to a far away place like DC they should only have DC travelers on the van or people on the way to DC. It took me 2 1/2 hours for a trip that would of taken take 45 minutes .
Very easy to find the pick up site from BWI airport. The lady dispatcher is very helpful and nice. There were 5 passengers in my ride, I was the 2nd to be drop off. The driver lady was nice too but she took extra cautiousness while driving every car passed us..., it took a little longer to go to my hotel, nevertheless, it's absolutely a safe ride.
It was hard to locate them at the airport as they no longer have the kiosk and only people who are walking around in blue jackets. Even then the person who was supposed to be there was not. Then I find out that my reservation through viator was not confirmed when I arrived which meant I had to wait an hour before I could even get on a van to the city.
