Are you talking about the special Holiday Rates emails MI used send to everyone around this time in years past? I haven't seen any of those, or any special rates for the Holidays yet this year, so I guess bookings are really up.
Alternatively, you could just type, "MEB," in the Corp/Promo Code box and check what is available in your area. At this rate a Friday or Sat night stay is required.
I have noticed the Marriott hotels in the DC area have lowered their rates considerably for the week between Xmas and New Year's, as low as $54 per night. Some of the rates are advanced purchase rates, however with no refunds 24 hours after booking.
