You may want to call the hotel and make sure their driver is doing his job... I got left for 2 1/2 hours waiting for them. The hotel stated it was because I didn't call and put bblame on me when they are supposed to be at airport every 30 minutes
It is 24 hour shuttle to Dulles. It is one of the few airport hotels that offer that.
5am through 11pm every 30min
