AaronJB - Thanks! Should work perfectly for our plans: flying into BWI at 10pm, next day - cruise out of Baltimore. Was looking for a nice hotel at the airport w/free shuttle to spend the night... Was considering 2.5* Wingate at $109 (plus tax) B) , then realized that this is a perfect "Priceline case"!! Looked at this forum, started bidding - lots of re-bid zones if you want a 3.5* in BWI airport zone. $65 did it! Am very happy
