Our family has done this a few times, in The Slieve Russell Hotel in Cavan, The Ferrycarrig in Wexford and The Westport Woods Hotel. All the weekends have been successful but of the 3, I think Westport was probably the best, especially where the children were concerned. The others would be "posher" but Westport was ahead on things to do, places to see and had the best hotel staff in terms of helpfulness and friendliness. Pretty reasonably priced too. Worked out at €1875 last June Bank Hol weekend for 9 adults and 8 children ( 2 night B&B + 1 dinner).
