We had the misfortune to be stuck at the airport arriving late one night and not having the will or energy to go into the city. The nearest option was the Park Plaza. The room was a very expensive 100 pounds. Whilst reasonably comfortable the window could not close properly so we were treated to the sound of the wind howling in off the lough all night, and a noisy party from the bar's garden downstairs.
The only good thing I can say it's situated less than 100 yards from the airport terminal.
