3 nights should not be that hard. If work travel won't get you there, you can always do a "mattress run," at a nearby Marriott. Marriott's E Breaks can offer some decent rates (Rate code MEB). Around Washington, DC weekend rates can some times be as low as $59 per night in the outlying 'burbs. (Just make sure your book on Marriott.com so you get properly credited for the nights you stay. You can look at other booking sites and use any lower rates you find to file a LNF claim to lower your rate even further.) You don't even need to stay overnight at the hotel (but friends or family may enjoy a mini stacation).

Others may do it differently, but when I do a mattress run, I check-in on my arrival night (you must show up at the hotel), go to the room and hang the, "Do not disturb," sign on the door. Call the front desk on the morning I am supposed to check out and tell them I forgot to drop the keys at the FD and the DND is still on the door, etc. They will check you out, with out any issues.
