The Castlecourt Hotel in Westport is doing very good deals as far as I'm aware. Their sister hotel, beside them, (I think it's the "Westport") also does good deals but not quite as good as the Castlecourt. Believe it or not, Knockranny House Hotel (which is normally a very upmarket/expensive hotel) is doing deals also, as far as I am aware. Knockranny is also a sister company of Castlecourt. From what I overheard when I stayed in Knockranny recently, if someone is staying in the Castlecourt or Westport, they can take advantage of the facilities at Knockranny. I would recommend you start with the Castlecourt.
