I am planning on parking at Dulles for about 13 days next month and was hoping to get some feedback on options. Have looked on the Dulles website and it appears as though the airport's offerings are only for 24hrs even long-term...or maybe I am misreading something here:

'Economy Parking (Long-term) is available in the four economy parking lots (Blue, Green, Gold and Purple) located along Rudder Road.
$3 per hour or fraction;
$9 maximum for 24 hours.'

So 13 days here is no good?

I am used to dealing with LHR & LGW where there are literally dozens options for long term parking! So hopefully experience of people here will pay off

We are looking to park the car in long term parking (wherever that may be) before going to the Hyatt Regency at Reston where we are staying before our flight the next day. Is the best way to do this to take the shuttle from the parking lot to the airport and then a Hyatt shuttle back to the hotel?

Thanks
