We booked a deluxe room at the BWI and got the $500 off 5 nights rate (we actually are staying 8 nights and the price is off per night, so we got $800 off). It isn’t as much as the AP discount, which unfortunately I have not been able to get, but I was happy to at least get something off! I wouldn’t plan a trip for it, but since our last 2 trips have been rack rate (which I have never ever had to do in the past!) I was happy to get something.
