I'm going to be in Ireland from approx 13 March to 21 March and need a good, inexpensive hostel in Dublin. The only problem is that it's St Paddy's day and anything decent is booked. I can find somewhere for 13-15 March and 18-21 March but having trouble with other days. I've looked at some of the nearby towns but they also seem to be full. Has anyone stayed in any of the outer villages, towns that they could recommend. I dont mind spending say 4 days in Dublin and the rest of the time somewhere else.
