Agree with others about NOT staying at National Harbor. Waiting for a hotel shuttle bus to take you to the metro could take forever. I think if you were only there for a day it would be fine but not a week. I recommend looking in Arlington for a hotel off the Orange metro line or looking for an apartment to rent off the Orange line.
You might want to buy a smart card. That saves you money versus buying a paper metro ticket. I am not familiar with unlimited tickets so that might be an option.
Do not even bother trying to drive in. You will regret it.
There is a neat museum in Chantilly, VA. It is the second Air and Space museum. It is free but they charge around $15.00 to park. Mount Vernon is a must see as well when you are here.
