Supershuttle bus arrived on time and got us to Dulles airport in a death defying ride. Getting confirmation of our return journey was a nightmare. I tried several ways to get pick up time online but it was impossible. I had to use my phone , at a cost of 12, to be given a code number for driver from a very unfriendly assistant.
Great driver. Very friendly. Willing to schedule me for an earlier time than their recommended time, as I was worried about getting through security. Picked me up in the time frame they said they would and got me to the airport in plenty of time. 5 stars!
