So when I land (at IAD) I just call the hotel, ask for a shuttle to come pick me up, and wait at gate 2Aoutside of baggage claim until x:15 or x:45 o'clock, and they'll take me to the hotel? I really hope I'm not missing something here.
Almo, I'm pretty sure the shuttle just comes and goes every half hour. Though it wouldn't hurt to call the hotel to find how early/late they're running.
