[broken link removed] are currently doing great deals where you can book two nights for the price of 1 up until the end of Feb - got meself a nice break for two in Barcelona at the end of the month (including Ryanair flights) for only €280 - sure you'd pay that for a weekend for two in Ennis! (no offence to Ennis ye understand!!)
