We booked for 10 people in the West back in August and even at that stage found that there were an awful lot of very organised people who had booked way ahead of us!
Go to West or East Cork ,No problem getting houses.Ring the Cork Kerry Tourism Office and they will sort you out with quality approved houses immediatly instead of messing around.
Why not try this place here in Killarney www.oldkillarney.com . We stayed there during the summer its about a mile and a half from the centre of killarney and there is a Bar & Restaurant onsite.
