Hard to beat a weekend in Galway - I came to college here nearly 20 years ago and never left the place....

Easy/cheap to get to - great pubs, clubs and plenty of events to cater for all tastes (Pallas Karting is great for the petrol-heads).

Good range of accomodation too (from really good hostels to 5*)
