I organised my own brothers stag last year and we went to Carlingford. If you want to PM me I will give you the number for a fantastic house. We had 12 all in and I was able to collect €150 a head which covered food (chipper one night and steak and a pint the following), 2 nights in the house and a fridge filled with a few slabs of cans and of course the stag. Everybody had great craic and it offered something for everyone. Activities are numerous and you would need about €60 a head for something like 4 x 4 off roading. As I say PM me if you want and I can give you more details.
