I just noticed that there are some special Tax Day rates going on at some of the Marriott properties in WDC. The rates are valid from May 23rd through Sept. 2nd and must involve a weekend. Book by April 21st. I booked a Fri. through Tues. Some of the hotels include: Washington Mayflower, Washington Marriott Georgetown and Crystal Gateway Marriott. There may be more properties; I didn't check all of them. I know that some on this forum have scored even better deals, but this is still good.
